Catena-Poly[[[aqua-copper(II)]-bis-[?-N,N'-bis-(pyridin-4-yl)isophthalamide]-[aqua-copper(II)]-di-?-sulfato] dimethyl-formamide disolvate].

ABSTRACT: In the title coordination polymer, {[Cu(SO4)(C18H14N4O2)(H2O)]·C3H7NO} n , the Cu(II) ion is coordinated by two N atoms of two briding N,N'-bis-(pyridin-4-yl)isophthalamide ligands, two O atoms of two bridging SO4(2-) anions and a water mol-ecule, giving a distorted CuN2O3 square-pyramidal geometry. The whole repeating mol-ecular unit is generated by inversion symmetry. This leads to the formation of a looped-chain one-dimensional coordination polymer propagating along [110]. The dimethyl-formamide (DMF) mol-ecules are linked to the chains via O-H?O hydrogen bonds. The chains are linked via N-H?O hydrogen bonds, forming two-dimensional networks parallel to (001). There are also a number of C-H?O inter-actions present and a parallel slipped ?-? inter-action. The latter involves inversion-related pyridine rings with a centroid-centroid distance of 3.594?(2)?Å [normal distance = 3.3338?(13) and slippage = 1.341?Å]. These inter-actions lead to the formation of a three-dimensional structure.
