The controlled crystallization of specific tantalum oxide-fluoride and tantalum fluoride anions ([TaOF5]2-, [TaF 6]-, and [TaF7]2-) is demonstrated using organic reagents with varied corresponding pKa values in the presence of aqueous hydrofluoric acid. The identity of tantalum oxide-fluoride or fluoride anions of [TaOF5]2-, [TaF6] -, and [TaF7]2- are shown to crystallize successively from solution to solid state by increasing the corresponding pKa of organic reagents, which lead to the subsequent increase of fluoride concentration in the hydrofluoric acid solution. With the use of this methodology, three new hybrid crystal structures were targeted: [H 2(2,2?-bpy)]TaOF5 (2,2?-bpy = 2,2?-bipyridyl) 1, [Hdpa]TaF6 (dpa = 2,2?-dipyridylamine) 2, and [H2En]TaF7 (En = ethylenediamine) 3, respectively. The applicability and comparison of this methodology for tantalum and previously prepared niobium compounds show that it can be broadly used to design new materials with specific functionalities for other transition metal oxide-fluorides.

We consider coordination compounds of ions with unfilled up 3d- and 4f-shell in a weak or intermediary crystalline field, containing dimer clusters in the case when the distance between clusters is more than the distance between the ions forming the cluster. In this case it is possible to neglect the exchange interaction between electrons of different clusters and the structure of the ground state of separate dimer is determined by the intercluster exchange, spin orbital, magnetic dipole?dipole, and hyperfine interactions. The presence of other dimers in the crystal is possible to take into account if populations of energy levels of system upon interacting dimer clusters are calculated.

The carboxyl-linked 24-glucuronides of common bile acids have been identified by means of liquid chromatography (LC)/atmospheric pressure chemical ionization (APCI)-mass spectrometry (MS) in an incubation mixture with a male Wistar rat liver microsomal fraction. The authentic specimens of bile acid 24-glucuronide acetate-methyl esters were synthesized unequivocally using the Mitsunobu reaction, and the APCI-mass spectrometric properties of these glucuronide derivatives were also characterized. After incubation of common unconjugated bile acids with hepatic microsomes, glucuronides were extracted and purified with a Sep-Pak C18 cartridge and lipophilic ion exchange gel, piperidino-hydroxypropyl Sephadex LH-20, and then derivatized into the acetate-methyl esters. Subsequent resolution into alpha- and beta- isomers at the glucuronosyl linkage was attained by LC on Cosmosil 5C8 and Sumichiral OA-2500 columns using 200 mM ammonium acetate (pH 7.0)-methanol (1:4, v/v), where 24-glucuronides were monitored with characteristic positive ions [M + NH4]+. The 24-glucuronides of lithocholic, chenodeoxycholic, deoxycholic, ursodeoxycholic and cholic acid were definitely characterized, in contrast to no formation of corresponding 3-glucuronides.

Researchers are common within chemical engineering and are often tasked with creating and developing new chemical techniques, frequently combining other advanced and emerging scientific areas. Introducing a new discovery about 499-40-1, Name is (2R,3S,4R,5R)-2,3,4,5-Tetrahydroxy-6-(((2S,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)hexanal, category: Tetrahydropyrans.

In the title dinuclear acetate-bridged complex, [Cu2(C2H3O2)3(NCS)(C10H9N3) 2], the two Cu atoms are five-coordinated, with a basal plane consisting of two N atoms of a di-2-pyridylamine (dpyam) ligand and two O atoms of two different acetate ligands. The axial positions of these Cu atoms are coordinated to N and O atoms from thio-cyanate and acetate mol-ecules, respectively, leading to a distorted square-pyramidal geometry with values of 0.30 and 0.22. Both Cu II ions are linked by an acetate group in the equatorial-equatorial positions and have syn-anti bridging configurations. Hydrogen-bond inter-actions between the amine H atom and the coordinated and uncoordinated O atoms of the acetate anions generate an infinite one-dimensional chain.
