Abstract: In the title compound, bis(-p-aminobenzoato-²O:O)bis[(N,N-dimethylformamide-O)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.
