Bis(2,2'-bipyridine-κN,N')(4-methyl-benzoato-κO,O')copper(II) iodide hemihydrate. | LitMetric
The title compound, [Cu(C(8)H(7)O(2))(C(10)H(8)N(2))(2)]I·0.5H(2)O, was obtained by the hydro-thermal reaction of copper(I) iodide, 4-methyl-benzoic acid and 2,2'-bipyridine. The initial reactant of Cu(I) was oxidized to Cu(II). The asymmetric unit contains two independent complex mol-ecules, two I(-) ions and one water molecule. Each Cu(II) atom is coordinated by two O atoms from a 4-methyl-benzoate ligand and four N atoms from two 2,2'-bipyridine ligands, displaying a distorted octa-hedral geometry. The structure involves O-H⋯I hydrogen bonds between the water mol-ecule and iodide ions and π-π stacking inter-actions between the benzene and pyridyl rings [centroid-centroid distance = 3.79 (1) Å] and between the pyridyl rings [centroid-centroid distance = 3.87 (1) Å].
