Diaqua-bis-(4-bromo-benzoato-κO)bis-(nicotinamide-κN)copper(II).

Abstract: The title NiII complex, [Ni(C7H4BrO2)2(C6H6N2O)2(H2O)2], is centrosymmetric. It contains two 2-bromo­benzoate (BB) ligands, two nicotinamide (NA) ligands and two water mol­ecules, all of them being monodentate. The four O atoms in the equatorial plane around the Ni atom form a slightly distorted square-planar arrangement, while the slightly distorted octa­hedral coordination is completed by the two N atoms of the NA ligands in the axial positions. The dihedral angle between the carboxyl­ate group and the adjacent benzene ring is 30.81 (17)°, while the pyridine and benzene rings are oriented at a dihedral angle of 84.66 (6)°. In the crystal structure, O—H⋯O and N—H⋯O hydrogen bonds link the mol­ecules into a supra­molecular structure. A weak C—H⋯π inter­action is also found.

Diaqua­bis(2-chloro­benzoato-κO)bis­(N,N-diethyl­nicotinamide-κN1)manganese(II)

Abstract: In the monomeric title complex, [Mn(C7H4ClO2)2(C10H14N2O)2(H2O)2], the MnII atom is located on a crystallographic centre of inversion. The asymmetric unit contains one 2-chloro­benzoate (CB) ligand, one diethyl­nicotinamide (DENA) ligand and one coordinated water mol­ecule, 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 octa­hedral 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, inter­molecular O—H⋯O hydrogen bonds link the mol­ecules into infinite chains.

Diaqua­bis(2-bromo­benzoato-κO)bis­(N,N-diethyl­nicotinamide-κN1)zinc(II)

Abstract: In the centrosymmetric title complex, [Zn(C7H4BrO2)2(C10H14N2O)2(H2O)2], the ZnII atom is located on an inversion center. The asymmetric unit contains one 2-bromo­benzoate (BB), one diethyl­nicotinamide (DENA) ligand and one coordinating water molecule. The four O atoms in the equatorial plane around the Zn atom form a slightly distorted square-planar arrangement, while the slightly distorted octa­hedral coordination is completed by the two N atoms of the DENA ligands in the axial positions. The dihedral angle between the carboxyl group and the adjacent benzene ring is 85.51 (12)°, while the pyridine and benzene rings are oriented at a dihedral angle of 44.07 (6)°. In the crystal structure, O—H⋯O hydrogen bonds link the mol­ecules into infinite chains.
