catena-Poly[[(2,2'-diamino-4,4'-bithiazole){μ3-cis-N-(2-carboxylatophenyl)-N'-[3-(dimethylamino)propyl]oxamidato(3-)}dicopper(II)] nitrate 0.6-hydrate].
The title complex, {[Cu(2)(C(14)H(16)N(3)O(4))(C(6)H(6)N(4)S(2))]NO(3)·0.6H(2)O}(n), is a one-dimensional copper(II) coordination polymer bridged by cis-oxamide and carboxylate groups. The asymmetric unit is composed of a dinuclear copper(II) cation, [Cu(2)(dmapob)(dabt)](+) {dmapob is N-(2-carboxylatophenyl)-N'-[3-(dimethylamino)propyl]oxamidate and dabt is 2,2'-diamino-4,4'-bithiazole}, one nitrate anion and one partially occupied site for a solvent water molecule. The two Cu(II) ions are located in square-planar and square-pyramidal coordination environments, respectively. The separations of the Cu atoms bridged by oxamide and carboxylate groups are 5.2053 (3) and 5.0971 (4) Å, respectively. The complex chains are linked by classical hydrogen bonds to form a layer and then assembled by π-π stacking interactions into a three-dimensional network. The influence of the terminal ligand on the structure of the complex is discussed.
