Diaqua-bis(5-bromo-2-hydroxy-benzoato)bis-(N-methyl-nicotinamide)zinc(II).

ABSTRACT: The title mononuclear complex mol-ecule, [Zn(C(7)H(4)BrO(3))(2)(C(7)H(8)N(2)O)(2)(H(2)O)(2)], has a crystallographically imposed centre of symmetry. The zinc(II) atom is coordinated by two N atoms from two N-methyl-nicotinamide ligands, two O atoms from two 5-bromo-salicylate anions and two aqua O atoms in a slightly distorted octa-hedral geometry. Intra-molecular O-H?O hydrogen-bonding inter-actions are present. In the crystal structure, mol-ecules are linked by inter-molecular O-H?O and N-H?O hydrogen bonds, forming a two-dimensional network perpendicular to [100].

Project description:The title Zn(II) complex, [Zn(C(7)H(4)BrO(2))(2)(C(6)H(6)N(2)O)(2)(H(2)O)(2)], is centrosymmetric with the Zn atom on an inversion center. The mol-ecule contains two 2-bromo-benzoate (BB) and two nicotinamide (NA) ligands and two coordinated water mol-ecules, all ligands being monodentate. 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 NA ligands in the axial positions. The dihedral angle between the carboxyl group and the adjacent benzene ring is 31.14?(12)°, while the pyridine and benzene rings are oriented at a dihedral angle of 83.54?(5)°. In the crystal structure, O-H?O and N-H?O hydrogen bonds link the mol-ecules into infinite chains. A weak C-H?? inter-action is also present.

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.

The ?-? contact between the benzene rings [centroid-centroid distance = 3.896?(1)?Å] may further stabilize the crystal structure. A weak C-H?? inter-action involving the pyridine ring also occurs.
