Poly[[[μ-1,4-bis(pyridin-4-ylmethyl)piperazine][μ-4-(2-carboxylatoethyl)benzoato]copper(II)] monohydrate], a coordination polymer with twofold interpenetrated cds topology networks

Abstract

The title compound, {[Cu(C10H8O4)(C16H20N4)]·H2O} n , contains square-planar coordinated CuII ions linked by 4-(carboxylatoethyl)benzoato (ceb) and 1,4-bis(pyridin-4-ylmethyl)piperazine (bpmp) ligands into a tri-periodic coordination polymer with twofold interpenetrating 658 cds topology. Positional crystallographic disorder among the copper atoms, the ethylcarboxy group of the ceb ligands, and the water molecules of crystallization exists in a refined 0.655 (6)/0.345 (6) ratio.
