Bis(4-fluorobenzoato-κ2 O,O′)bis(nicotinamide-κN 1)zinc(II) monohydrate

چکیده
The title compound, [Zn(C(7)H(4)FO(2))(2)(C(6)H(6)N(2)O)(2)]·H(2)O, is a monomeric complex. It contains two 4-fluoro-benzoate and two nicotinamide ligands and one uncoordinated water mol-ecule. The 4-fluoro-benzoates act as bidentate chelating ligands, while the nicotinamides are monodentate. The six-coordinate geometry around the Zn(II) atom may be described as highly distorted octa-hedral, with the two nicotinamide ligands arranged cis. Inter-molecular O-H⋯O and N-H⋯O hydrogen bonds link the mol-ecules into a supra-molecular structure.

The crystal structure of the title compound, [Zn(2)(C(8)H(7)O(2))(4)(H(2)O)(2)]·[Zn(2)(C(8)H(7)O(2))(4)(C(6)H(6)N(2)O)(2)]·2H(2)O, consists of two kinds of dinuclear Zn(II) complexes (complex A and complex B) and uncoordinated water mol-ecules. In complex A, [Zn(2)(C(8)H(7)O(2))(4)(H(2)O)(2)], each Zn cation is chelated by a 4-methyl-benzoate (PMB) anion and coordinated by a water mol-ecule, an...

The title material, [Zn(C(5)H(7)O(2))(2)(C(9)H(9)NO)], was synthesized by the treatment of bis-(acetyl-acetonato)zinc(II) monohydrate with 2-phenyl-2-oxazoline. The Zn atom is coordinated by two chelating acetyl-acetonate groups and one oxazoline ligand in the apical position of a slightly distorted square-pyramidal metal-ligand geometry.
