摘要

We herein report three new coordination polymers generated from Cu(II) carboxylates (mal, 2ac, fum) and conformationally flexible bifunctional IX as building blocks. All the three complexes adopt unique structures in the solid state. The complex [Cu-2(mal)(2)(IX)(2)(H2O)(6)](n) crystallizes as orthorhombic co-linear rods with space group P2(1) P2(1) P2(1). Each rod is further formed of two tightly intertwined strings. The second polymer [Cu-2(ac)(4)(IX)(2)](n) crystallizes with space group P1 which consists of two sets of intersecting 2D sheets composed of parallel rods which interpenetrate to form a fully interlocked 3D structure. In both these complexes IX coordinates in the anti mode. The third polymer [Cu-2(fum)(2)(IX)(2)(H2O)(2)](n) possesses a monoclinic crystal system with space group C-2/c and crystallizes as 1D straps. Cu-fum-Cu forms the base of the string which is alternatively garlanded by a macrocycle derived from Cu-2(IX)(2) unit, where IX coordinates in the syn fashion. The present study suggests that the use of a rigid building block with a flexible organic ligand leads to a better prediction of the final structure of the polymeric array. (C) 2004 Elsevier Ltd.
