The title compound, [Cu(C₅H₈N₂)(C₁₄H₂₃N₅O)](ClO₄)₂, consists of a five-coordinate square-pyramidal copper(II) complex as its perchlorate salt. The copper(II) ion is coordinated in the basal plane by azole and amine N atoms of the N,N-bis(3,5-dimethyl-1-pyrazol)methyl]-1-hydroxy-2-aminoethane (bpmhe) ligand and 3,5-dimethylpyrazole, and in the apical position by an alcohol O atom.

Two Tc-containing products were isolated from the reaction between CS₂ and the electron-deficient complex TcCl(dppe)₂. The title di­thio­formate complex, [Tc(S₂CH)(dppe)₂]·3C₆H₆, where dppe is 1,2-bis­(di­phenyl­phosphino)­ethane (C₂₆H₂₄P₂), exhibits Tc-P bond lengths ranging from 2.3566 (14) to 2.3884 (14) Å, which are little shorter than normally found. The other product is [TcCl(CS)(dppe)₂], and is the first reported Tc-thio­carbonyl complex.

The title compound, chloro­bis­[1,2-ethanediyl­bis­(di­phenyl­phos­phine)-P,P'](thio­carbonyl-C)­technetium benzene sol­vate, [TcCl(C₄₆H₄₂P₄)(CS)]·C₆H₆, was obtained as one of two Tc-containing products isolated from the reaction between CS₂ and the electron-deficient complex [TcCl(dppe)₂], where dppe is 1,2-ethane­diyl­bis­(di­phenyl­phosphine). The structure exhibits an unusually short Tc-C distance [1.819 (6) Å], suggesting some multiple-bond character.

Structure analysis of the title compound, C₉H₆BrNO, has established that bromination of an 8-hydroxyquinoline derivative occurred in the 7-position. Intermolecular and weak intramolecular O-HN hydrogen bonds are present, the former causing the mol­ecules to pack as hydrogen-bonded dimers in the solid state.

The title compound, C₂₉H₄₅Cl₃NO·0.5C₅H₁₂O, is a rare example of a crystalline tri­chloro­acetimidate and has a structure similar to that reported for analogous species.

The crystal structure of 2-O-[17-oxoestra-1,3,5(10)-trien-3-yl]--D-glucopyranosiduronic acid hydrate, C₂₄H₃₀O₈.H₂O, is reported. The angle between the mean plane of the A ring of the steroid and the mean plane of the glucuronide is 14.1 (5)°.

The title compound, [RuCl₂(C₁₂H₁₈)(C₅H₅N)], crystallizes with two discrete independent molecules per asymmetric unit. In each molecule the Ru atom displays a `piano stool' configuration.

In the title compound, [Os(C₁₀H₁₄)Cl₂(C₁₈H₃₁P)], The presence of bulky substituents imposes a structural distortion on the (2,4,6-tri-tert-butyl­phenyl)­phosphine ligand, which is bowed.

In the title compound, [RhCl₂(C₁₀H₁₅)(C₅H₅N)], the Rh atom displays a piano-stool configuration. The two halves of the mol­ecule are related by mirror symmetry.

The crystal structure of the title compound, [Zn(C₅₀H₅₈N₆)]·CHCl₃, reveals a polymeric chain in a zigzag conformation, with a single pyridyl group from each porphyrin making the connection.
