Diaqua-bis(2-chloro-benzoato-κO)bis-(N,N-diethyl-nicotinamide-κN)nickel(II)
Abstract:
In the monomeric and centrosymmetric title Ni(II) complex, [Ni(C(7)H(4)ClO(2))(2)(C(10)H(14)N(2)O)(2)(H(2)O)(2)], the Ni(II) ion is located on an inversion center. The asymmetric unit contains one 2-chloro-benzoate ligand, one diethyl-nicotinamide (DENA) ligand and one coordinating water mol-ecule, the ligands being monodentate. The four O atoms in the equatorial plane around the Ni(II) ion form a slightly distorted square-planar arrangement, while the slightly distorted octa-hedral coordination is completed by two N atoms of the DENA ligands in axial positions. The dihedral angle between the benzene ring and the attached carboxyl-ate group is 87.36 (10)°, while the pyridine and benzene rings are oriented at an angle of 41.90 (5)°. In the crystal structure, inter-molecular O-H⋯O hydrogen bonds link the mol-ecules into a two-dimensional network parallel to (10).

Structural Isomerism
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can be...
Precipitation Gravimetry
In determining nickel by gravimetric analysis, a precipitant of ethanolic dimethylglyoxime is added to a hot nickel salt solution. This is quickly followed by the dropwise addition of dilute ammonia solution until precipitation occurs. A...
Metal-Ligand Bonds
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...
