ABSTRACT
The title complexes, catena-poly[[[diaquadiethanolmanganese(II)]-mu-1,4-bis(diphenylphosphinoyl)butane-kappa(2)OO'] dinitrate 1,4-bis(diphenylphosphinoyl)butane solvate], {[Mn(C(2)H(6)O)(2)(C(28)H(28)O(2)P(2))(H(2)O)(2)](NO(3))(2).C(28)H(28)O(2)P(2)}(n), (I), and catena-poly[[[diaquadiethanolcobalt(II)]-mu-1,4-bis(diphenylphosphinoyl)butane-kappa(2)OO'] dinitrate 1,4-bis(diphenylphosphinoyl)butane solvate], {[Co(C(2)H(6)O)(2)(C(28)H(28)O(2)P(2))(H(2)O)(2)](NO(3))(2).C(28)H(28)O(2)P(2)}(n), (II), are isostructural and centrosymmetric, with the M(II) ions at centres of inversion. The coordination geometry is octahedral, with each metal ion coordinated by two trans ethanol molecules, two trans water molecules and two bridging 1,4-bis(diphenylphosphinoyl)butane ligands which link the coordination centres to form one-dimensional polymeric chains. Parallel chains are linked by hydrogen bonds to uncoordinated 1,4-bis(diphenylphosphinoyl)butane molecules, which are bisected by a centre of inversion. Further hydrogen bonds, weak C-H...O interactions to nitrate anions, and weak C-H...pi interactions serve to stabilize the structure. This study reports a development of the coordination chemistry of bis(diphenylphosphinoyl)alkanes, with the first reported structures of complexes of the first-row transition metals with 1,4-bis(diphenylphosphinoyl)butane.
