catena-Poly[[(μ-4,4′-bipyridine-κ²N:N′)bis[aqua(dimethylformamide-κO)copper(II)]]-di-μ-terephthalato-κ⁴O¹:O⁴]

Abstract

The title coordination polymer, [Cu2(C8H4O4)2(C10H8N2)(C3H7NO)2(H2O)2]n, adopts a ladder structure in which terephthalate functions as the rails and bipyridine, lying on inversion centres, as the rungs. The Cu atom is also coordinated by water and dimethylformamide molecules in a square‐pyramidal environment. Hydrogen bonds link the ladders into a three‐dimensional network.

“…3) and c g ···c g distance (Janiak, 2000) is 4.17 Å. The similar supramolecular synthons R 2 2 (10) and R 2 2 (12) (Bernstein et al, 1995) have been also observed in crystal structure of one dinuclear complex (Valigura et al, 2006) and several polymeric complexes (Abourahma et al, 2002;Burrows et al, 2008;Cao et al, 2008;Korabik et al, 2011;Maharramov et al, 2012;Vaskova et al, 2011;Xu et al, 2007;Yamada et al, 1998). The crystal packing of 1 is shown in Fig.…”
