(4,4'-Dimethyl-2,2'-bipyridine-?N,N')diiodidomercury(II).

ABSTRACT: In the mol-ecule of the title compound, [HgI(2)(C(12)H(12)N(2))], the Hg(II) atom is four-coordinated in a distorted tetra-hedral configuration by two N atoms from the 4,4'-dimethyl-2,2'-bipyridine ligand and by two I atoms. There is a ?-? contact between the pyridine rings [centroid-centroid distance = 3.775?(6)?Å].

(Benzoato-κO)(benzoic acid-κO)(4,4'-dimethyl-2,2'-bipyridine-κN,N')hydroxidocopper(II) monohydrate.

Project description:In the structure of the title complex, [Cu(C(7)H(5)O(2))(OH)(C(12)H(12)N(2))(C(7)H(6)O(2))]·H(2)O, the Cu(II) ion is penta-coordinated in a tetra-gonal-pyramidal geometry with one O atom of a hydroxide group, one O atom of a benzoate anion and two N atoms of a 4,4'-dimethyl-2,2'-bipyridine ligand occupying the basal plane, and one O atom of a benzoic acid mol-ecule located at the apical site. The title complex was refined with a metal-coordinated OH group and a 'free' benzoic acid molecule, although it can be assumed that the proton is delocalized between the OH and the COOH group. The uncoordinated water mol-ecule is equally disordered over two positions. The structure displays O-H⋯O hydrogen bonding.
