Diaqua-bis(2-chloro-benzoato-?O)bis-(N,N-diethyl-nicotinamide-?N)manganese(II).

ABSTRACT: In the monomeric title complex, [Mn(C(7)H(4)ClO(2))(2)(C(10)H(14)N(2)O)(2)(H(2)O)(2)], the Mn(II) atom is located on a crystallographic centre of inversion. The asymmetric unit contains one 2-chloro-benzoate (CB) ligand, one diethyl-nicotinamide (DENA) ligand and one coordinated water mol-ecule, all ligands being monodentate. The four O atoms in the equatorial plane around the Mn atom form a slightly distorted square-planar arrangement, while the slightly distorted octa-hedral coordination is completed by the two pyridine N atoms of the DENA ligands in the axial positions. The dihedral angle between the carboxyl group and the adjacent benzene ring is 77.9?(11)°, while the pyridine and benzene rings are oriented at a dihedral angle of 45.94?(5)°. In the crystal structure, inter-molecular O-H?O hydrogen bonds link the mol-ecules into infinite chains.
