A dinuclear copper complex with a p-amino­benzoate anion

In the title compound, bis(μ-p-aminobenzoato-κ²O:O)bis[(N,N-dimethylformamide-κO)copper(II)], [Cu₂(L)₄(DMF)₂]·2DMF (HL is p-amino­benzoic acid, C₇H₆NO₂, and DMF is N,N-dimethyl­formamide, C₃H₇NO), two Cu^II cations are bridged by four L⁻ anions to form a dinuclear complex that lies on a center of inversion. The Cu^II cation is coordinated by four carboxyl­ate O atoms from four L⁻ anions and one O atom from a DMF molecule. A free DMF molecule is present in the asymmetric unit. The L⁻ anions and the uncoordinated DMF molecules are linked through hydrogen bonds to form a one-dimensional structure along the c axis.

Tetra­kis(3,5-diphenyl-4-amino-4H-1,2,4-triazole-κN¹)zinc(II) bis­(perchlorate)

In the title compound, [Zn(C₁₄H₁₂N₄)₄](ClO₄)₂, the Zn atom is coordinated tetra­hedrally by four monodentate 3,5-diphenyl-4-amino-4H-1,2,4-triazole ligands.

Diaqua­bis(1,10-phenanthroline-κ²N,N′)zinc(II) penta­fluoro­oxoniobate(V)

The crystal structure of the title compound, [Zn(C₁₂H₈N₂)₂(H₂O)₂][NbF₅O], consists of Zn^II complex cations and Nb^V complex anions. The Zn^II and Nb^V atoms each have a distorted octa­hedral coordination geometry. The Nb—F bond in the trans position with respect to the Nb=O bond is significantly longer than the other four Nb—F bonds in the same [NbOF₅]²⁻ anion.

Bis(1,10-phenanthroline)dithio­cyanato­zinc(II)

The title compound, [Zn(NCS)₂(C₁₂H₈N₂)₂], is a mononuclear zinc complex, in which the Zn atom is located on a twofold rotation axis. The zinc^II cation has a slightly distorted octa­hedral geometry containing four N atoms from two 1,10-phenanthroline mol­ecules and two N atoms from two thio­cyanate anions.
