Hexaaqua-manganese(II) bis-[4-(pyridin-2-ylmeth-oxy)benzoate] dihydrate.

ABSTRACT: The Mn(II) atom in the title salt, [Mn(H(2)O)(6)](C(13)H(10)NO(3))(2)·2H(2)O, lies on a center of inversion in an octa-hedron of water mol-ecules. The cations, anions and uncoordinated water mol-ecules are linked by O-H⋯O and O-H⋯N hydrogen bonds into a three-dimensional network. The anion is essentially planar, with an r.m.s. deviation of all non-H atoms of 0.068 Å.

Hexaaqua-manganese(II) bis-{[N-(3-meth-oxy-2-oxidobenzyl-idene)glycylglycinato]copper(II)} hexa-hydrate.

Project description:The ligand N-(2-hydr-oxy-3-methoxy-benzyl-idene)glycylglycine (H(3)L), a Schiff base derived from glycylglycine and 3-methoxy-salicylaldehyde, was used in the synthesis of a new organic-inorganic coordination complex, [Mn(H(2)O)(6)][Cu(C(12)H(11)N(2)O(5))](2)·6H(2)O. The Mn(II) atom is located on an inversion center and is coordinated to six water mol-ecules in a slightly distorted octa-hedral geometry. The Cu(II) atom is chelated by the tetra-dentate Schiff base ligand in a distorted CuN(2)O(2) square-planar coordination. In the crystal structure, the complex [Mn(H(2)O)(6)](2+) cations and the [CuL](-) anions are arranged in columns parallel to the a axis and are held together by O-H⋯O hydrogen bonding. Additional hydrogen bonds of the same type further link the columns into a three-dimensional network.
