چکیده
In the structure of the title compound, [Cu(2)(C(6)H(6)N(4))(2)(H(2)O)(2)]SO(4), the asymmetric unit contains half each of two 2,2'-diimidazole ligands, one Cu(+) cation, one water mol-ecule and half of a sulfate anion (2 symmetry). The dinuclear complex is completed through a twofold rotation axis, leading to a twisted ten-membered ring mol-ecule. The dihedral angle between the two symmetry-related 2,2'-diimidazole ligands is 23.6 (1)°. The copper centre is coordinated by two N atoms of two symmetry-related 2,2'-diimidazole ligands in an almost linear fashion. The water mol-ecule exhibits a weak coordination to Cu(+) with a more remote distance of 2.591 (2) Å. The distance between the two copper centres is 2.5956 (6) Å. O-H⋯O and N-H⋯O hydrogen bonds between the complex cation, the water mol-ecule and the sulfate anion lead to the formation of a three-dimensional network.

The title complex, [Ag(2)(C(10)H(8)N(2))(2)(C(32)H(30)N(2)P(2))](ClO(4))(2)·2CH(3)COCH(3), is a centrosymmetric dimer with pairs of Ag(I) atoms bridged by N,N'-bis-(diphenyl-phosphinometh-yl)ben-zene-1,4-diamine ligands. In addition, each Ag(I) atom is coordin-ated by one chelating 2,2'-bipyridine ligand, giving a distorted trigonal coordination environment.

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].
