Sažetak
Bis[bis{;(diphenylphosphinyl)methyl};ethyl phoshinate]bis(ethanol) metal(II) perchlorate complexes, where metal = Co, Ni or Cu, have been prepared by the reaction of metal perchlorates and bis[(diphenylphosphinyl)methyl]ethyl phosphinate, (RPOEt), in absolute ethanol. The crystal structure of the copper complex is triclinic, space group P, a = 13.688(7) Å, b = 14.424(10) Å, c = 9.865(2) Å, α = 110.43(4)°, β = 90.13(2)°, γ = 115.54(4)°, V = 1619.8 Å3, Z = 1 and refined to R = 0.048 (Rw = 0.057). The structure consists of complex cations surrounded by perchlorate anions. Two RPOEt ligands and two ethanols are coordinated to the copper atom situated at the centre of symmetry 0, 0, 0. The RPOEt ligand is bidentate [CuO distances 1.969(4) Å, 2.312(4) Å], but the third oxygen atom from phosphoryl bonds is hydrogen bonded [2.669(6) Å], to the oxygen atom of ethanol molecule coordinated to the copper at 1.988(4) Å. The conformations of the ligand and chelate rings, magnetic data, molar conductance values, infrared and electronic spectra are given.
