نویسنده
چکیده
In title compound, [Cu(C(8)H(7)O(2))(2)(C(6)H(6)N(4))(2)], the Cu(II) atom (site symmetry ) is coordinated by two N,N'-bidentate 2,2'-biimidazole ligands and two weakly bonded 4-methyl-benzoate anions, resulting in a strongly elongated trans-CuO(2)N(4) octa-hedral geometry. In the crystal, adjacent mol-ecules are linked via pairs of N-H⋯O hydrogen bonds into chains propagating in [010].

In the title copper(II) salt, [Cu(C(6)H(6)N(4))(2)(C(2)H(6)OS)(2)](BF(4))(2), the Jahn-Teller distorted octa-hedral coordination sphere of copper is formed from four 2,2'-bi-1H-imidazole N atoms and two dimethyl sulfoxide O atoms. The Cu atom lies on a center of inversion. N-H⋯O and N-H⋯F hydrogen bonds give rise to a one-dimensional structure. The BF(4) (-) anion is disordered over two sites i...

In the binuclear title compound, [Cu(2)(NO(2))(4)(C(4)H(6)N(2))(4)], centro-symmetric-ally related complex mol-ecules are linked via weak Cu-O inter-actions, forming dimeric units. The Cu(II) atom displays an elongated square-pyramidal CuN(2)O(3) coordination geometry with a slight tetra-hedral distortion of the basal plane [maximum deviation = 0.249 (2) Å]. The dihedral angle formed by the imi...
