A POLYMERIC COPPER(II) COMPLEX WITH 2,2'-BIPYRIDINE AND 1,2-BENZENEDICARBOXYLATE(2-)

catena-Poly[[aqua(bipyridine-kappa2N,N') mu-[1,2-benzene-dicarboxylato (2-)-kappaO:kappaO']] trihydrate, {[Cu2-(C8H4O4)2(C10H8N2)2(H2O)].3H2O }n, M(r) = 839.76, monoclinic, P2(1)/n, a = 12.902 (1), b = 20.561 (2) , c = 13.558 (6) angstrom, beta = 109.38 (2)-degrees, V = 3393 (2) ang strom3, Z = 4, D(x) = 1.64 g cm-3, lambda(Mo Kalpha) = 0.71069 angstro m, mu 13.27 cm-1, F(000) = 1720, T = 292 K, R = 0.0364 for 2834 indepe ndent reflections with I > 2sigma(I). The structure consists of Cu(C10 H8N2) and Cu(C10H8N2)(H2O) units linked in polymeric chains by two bri dging 1,2-benzenedicarboxylato(2-) anions. The chains are joined by Cu -O interaction forming double chains parallel to the c axis. Pentacoor dination of both Cu atoms involves two O atoms from different 1,2-benz enedicarboxylato ions and two N atoms from a 2,2'-bipyridine ligand an d at the apical site is another carboxylato O atom for the first Cu at om and the O atom of a water molecule for the second Cu atom. Water mo lecules which are not bonded to the Cu atom are situated-in channels p arallel to the b axis.
