Crystal structure of catena-poly[[copper(II)-μ2-salicylato-[diaqua­copper(II)]-μ2-salicylato] dihydrate]

[摘要] The title compound, {[Cu2(C7H4O3)2(H2O)2]·2H2O}n, contains two copper(II) cations in special positions (one on a twofold rotation axis and one on an inversion centre) and the the salicylate ligand in its dianionic form. By four- and six-coordinate metal coordination, chains are formed parallel to [001], which are extended by O—H⋯O hydrogen bonding into sheets extending parallel to (100). These sheets are weakly connected by O—H⋯O hydrogen bonding via the non-coordinating lattice water mol­ecules into a three-dimensional network.
