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.

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.

Bis(3-methyl­isoquinoline-κN)silver(I) nitrate

In the title compound, [Ag(C₁₀H₉N)₂]NO₃, the Ag^I cation, lying on a twofold rotation axis, is two-coordinated by two N atoms from two different 3-methyl­isoquinoline mol­ecules in a linear coordination. The nitrate anions do not coordinate to the Ag^I cations, but rather act as counter-anions. The title compound forms a two-dimensional supramolecular structure through π–π inter­actions between the 3-methyl­isoquinoline ligands.
