Diaqua-bis[4-(dimethyl-amino)benzoato-?O](isonicotinamide-?N)manganese(II).

ABSTRACT: The title Mn(II) complex, [Mn(C(9)H(10)NO(2))(2)(C(6)H(6)N(2)O)(H(2)O)(2)], contains two 4-(dimethylamino)benzoate (DMAB) anions, one isonicotinamide (INA) ligand and two coordinated water mol-ecules. One of the DMAB anions acts as a bidentate ligand, while the other is monodentate. The four O atoms in the equatorial plane around the Mn atom form a highly distorted square-planar arrangement, while the distorted octa-hedral coordination geometry is completed by the N atom of the INA ligand and the O atom of the second water mol-ecule in the axial positions. In the crystal structure, strong inter-molecular O-H?O, O-H?N and N-H?O hydrogen bonds link the mol-ecules into a two-dimensional network parallel to (010). Two weak C-H?? inter-actions are also found.

Project description:The mol-ecule of the title Zn(II) complex, [Zn(C(9)H(10)NO(2))(2)(C(6)H(6)N(2)O)(H(2)O)(2)], contains two 4-(dimethyl-amino)benzoate (DMAB) ligands, one isonicotinamide (INA) ligand and two water mol-ecules; one of the DMAB ions acts as a bidentate ligand while the other and INA are monodentate ligands. The four O atoms in the equatorial plane around the Zn atom form a distorted square-planar arrangement, while the distorted octa-hedral coordination is completed by the N atom of the INA ligand and the O atom of the water mol-ecule in the axial positions. Intra-molecular C-H?O hydrogen bonding results in the formation of a six-membered ring adopting an envelope conformation. The dihedral angle between the carboxyl groups and the adjacent benzene rings are 4.87?(16) and 2.2?(2)°, while the two benzene rings are oriented at a dihedral angle of 65.13?(8)°. The dihedral angle between the benzene and pyridine rings are 11.47?(7) and 74.83?(8)°, respectively. In the crystal structure, inter-molecular O-H?O, O-H?N and N-H?O hydrogen bonds link the mol-ecules into a supra-molecular structure. ?-? contacts between the pyridine and benzene rings and between the benzene rings [centroid-centroid distances = 3.695?(1) and 3.841?(1)?Å, respectively] further stabilize the structure. Weak inter-molecular C-H?? inter-actions are also present.
