Catena-poly[[[(1,10-phenanthroline-kappa(2)N,N')manganese(II)]-microL-tartrato-kappa(4)O(1),O(2):O(3),O(4)] hexahydrate

Abstract

The title compound, [[Mn(C(4)H(4)O(6))(C(12)H(8)N(2))].6H(2)O](n), has a linear chain structure containing monomeric [Mn(C(4)H(4)O(6))(C(12)H(8)N(2))] repeat units. Each manganese ion is six-coordinate, with the two phenanthroline N atoms [Mn-N = 2.229 (2) and 2.235 (2) A] and four O atoms from two tartrate anions [Mn-O(COO) = 2.1252 (19) and 2.1310 (19) A, and Mn-O(OH) = 2.2404 (19) and 2.2424 (19) A] forming a seriously distorted octahedral coordination environment. Six water molecules exist outside every repeat unit as solvate molecules. Extensive hydrogen-bonding interactions and pi-pi stacking of the phenanthroline moieties exist between the chains.
