Diaqua-bis(2-bromo-benzoato-?O)bis-(N,N-diethyl-nicotinamide-?N)zinc(II).

ABSTRACT: In the centrosymmetric title complex, [Zn(C(7)H(4)BrO(2))(2)(C(10)H(14)N(2)O)(2)(H(2)O)(2)], the Zn(II) atom is located on an inversion center. The asymmetric unit contains one 2-bromo-benzoate (BB), one diethyl-nicotinamide (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 octa-hedral 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 mol-ecules into infinite chains.

Diaqua-bis(4-bromo-benzoato-?O,O')zinc(II).

Project description:The monomeric title Zn(II) complex, [Zn(C(7)H(4)BrO(2))(2)(H(2)O)(2)], contains two 4-bromo-benzoate (BB) ligands and two coordinated water mol-ecules around a Zn(II) atom on a twofold rotation axis. The BB ions act as bidentate ligands, with two very dissimilar coordination distances. The sixfold coordination around the Zn(II) may be described as highly distorted octa-hedral, with the two aqua ligands arranged cis. Hydrogen bonding involving the carboxyl-ate O atoms has an effect on the delocalization in the carboxyl-ate groups. In the crystal structure, inter-molecular O-H?O hydrogen bonds link the mol-ecules into chains parallel to the c axis and stacked along the b axis.

Diaqua-bis-(N,N-diethyl-nicotinamide-?N(1))bis-(4-formyl-benzoato-?O(1))zinc.

Project description:In the title complex, [Zn(C(8)H(5)O(3))(2)(C(10)H(14)N(2)O)(2)(H(2)O)(2)], the Zn(II) cation is located on an inversion center and is coordinated by two 4-formyl-benzoate anions, two N,N-diethyl-nicotinamide (DENA) ligands and two water mol-ecules.

The dihedral angle between the carboxyl-ate group and the adjacent benzene ring is 2.96?(11)°, while the pyridine ring and the benzene ring are oriented at a dihedral angle of 79.26?(4)°. The coordinating water mol-ecule links with the carboxyl-ate group via an intra-molecular O-H?O hydrogen bond. In the crystal, O-H?O and weak C-H?O hydrogen bonds link the mol-ecules into a three-dimensional supra-molecular network. A ?-? contact between the parallel pyridine rings of adjacent mol-ecules may further stabilize the crystal structure [centroid-centroid distance = 3.5654?(8)?Å].
