By employing a flexible molecule, 2,2?-dipyridylamine (dpa), as a bidentate coligand, three azide-bridged one-dimensional coordination polymers, [M(dpa)(N3)2]n (M = Cu, 1 ·Cu; Co, 2·Co) and [Ni(dpa)(OAc)0.5(N3)1.5(H 20)]n (3-Ni), have been successfully synthesized and structurally and magnetically characterized. They show versatile one-dimensional chain structures. 1 ·Cu is an EO-N3 bridged uniform chain; 2·Co is an alternative chain linked by two EO-N3 and two EE-N3 bridges. Interestingly, 3·Ni is a zigzag chain linked alternatively by one EE-N3 and a novel 3-fold bridge, which is composed of two EO-N3 and one acetate group. This series of azido complexes demonstrates that the flexibility of the dpa ligand plays an important role in directing the structures of the final products. Magnetic studies reveal dominant intrachain antiferromagnetic couplings in compound 1 · Cu. Compounds 2·Co and 3·Ni are weak ferromagnets due to the spin canting, with critical temperatures of 12.4 and 32.5 K, respectively.

Abstract: A new water-soluble copper(II) complex bearing 4-bromobenzoate/2,2?-dipyridylamine ligands was successfully synthesized and characterized by using single crystal X-ray diffraction and spectroscopic techniques. The catalytic activity of the compound was investigated as a homogeneous catalyst in the oxidation of several alcohols (benzyl alcohol, cinnamyl alcohol, 1-phenylethanol, cyclohexanol, 1-heptanol) and alkenes (styrene, ethylbenzene, cyclohexene) in aqueous medium. The copper(II) catalyst was found to be active for the studied alcohols and alkenes. H 2O 2 was used as an active oxidant for alcohol oxidation, while t-BuOOH (TBHP) was used for alkenes. The compound exhibited high selectivity toward benzaldehyde (88%) in cinnamyl alcohol oxidation under mild conditions (70 ?C) after 4 h. Particularly, remarkable results were obtained for the oxidation of styrene and cyclohexene; transformation via allylic oxidation to 2-cyclohexene-1-one as one product in 2 h (TOF=50h-1) and benzaldehyde in 1 h (100% conversion, TOF = 86 h – 1, 100% selectivity). The Cu(II)/TBHP (or H 2O 2) / H 2O system proved to be an alternative for catalytic oxidations in the green chemistry concept. Graphical Abstract: New Copper(II)-complex bearing 4-bromobenzoate/2,2?-dipyridylamine ligands was synthesized and characterized by single crystal diffraction technique. The complex exhibited good catalytic oxidation activity on alcohols and alkenes in water, a green solvent. [Figure not available: see fulltext.].

The structures of in catena-poly[[(di-2-pyridylamine-kappa2N, N?)silver(I)]-mu-nicotinato-kappa2N:O], [Ag(C 6H4NO2)(C10H9N 3)]n was discussed. It was found that the Ag atom is tetracoordinated by two N atoms from the di-2-pyridylamine (BPA) ligand. A polymeric chain structure was generated, which extends along [100] by bridging nicotinate N and O atoms. The results show that the ribbons were linked between inversion-related pairs of 2,6-dihydroxybenzoate ligands to generate a three-dimensional network.

The crystal structure of Cs2[Co2(nta)2(mu-OH)2] · 4H2O (nta = nitrilotriacetate) has been determined from three-dimensional X-ray diffraction data. Two hydroxo groups act as bridging groups between the two Co metal centres. The Co – OH bond distances are 1.899(5) and 1.897(5) A, respectively and the Co – OH – Co bond angles 98.2(2). The nta ligand acts as a tetradentate ligand and bonds with a nitrogen as well as three oxygen atoms to the Co metal centre. The Co – N and Co – O(av) bonds are 1.922(6) and 1.895(5) A, respectively. (C10H10H3)2[CoCl4] consists of discrete monoprotonated 2,2?-iminodipyridinium cations and CoCl2-4 anions. The anions assume a regular tetrahedral geometry, with the Cl – Co – Cl bond angles varying between 107.34(10) and 112.07(10). The Co – Cl bond distances are 2.270(2) and 2.282(2) A, respectively. The two pyridine rings in the cation assume an almost planar orientation with a deviation of 7.7(6) for the dihedral angle between the two ring systems. The planar orientation can be attributed to weak hydrogen bonding between the unprotonated nitrogen atom of the one pyridine ring and the proton bonded to the other nitrogen atom on the adjacent ring.

In a Review，once mentioned of 499-40-1

Multidisciplinary research on organic fluorescent molecules has been attracting great interest owing to their potential applications in biomedical and material sciences. In recent years, electron deficient systems have been increasingly incorporated into fluorescent materials. Triarylboranes with the empty p orbital of their boron centres are electron deficient and can be used as strong electron acceptors in conjugated organic fluorescent materials. Moreover, their applications in optoelectronic devices, energy harvesting materials and anion sensing, due to their natural Lewis acidity and remarkable solid-state fluorescence properties, have also been investigated. Furthermore, fluorescent triarylborane-based materials have been commonly utilized as emitters and electron transporters in organic light emitting diode (OLED) applications. In this review, triarylborane-based small molecules and polymers will be surveyed, covering their structure-property relationships, intramolecular charge transfer properties and solid-state fluorescence quantum yields as functional emissive materials in OLEDs. Also, the importance of the boron atom in triarylborane compounds is emphasized to address the key issues of both fluorescent emitters and their host materials for the construction of high-performance OLEDs.
