Full description

Complexes [ XCu ( py )(PPh3)2], X = Cl, Br, I, py = pyridine, have been synthesized and characterized by single-crystal X-ray structure determition. Chloride and iodide derivatives have similar cells [ isomorphous (?) but not isostructural ], triclinic, pi, a = 19.5 A, b = 10.5, c = 9.6 Š, a 蠶6, ߠ蠸6, ? 蠸3ꬠZ = 2; the bromide is monoclinic, Cc, a 13.568(9), b 15.760(12), c 16.545(8) Š, ߠ95.65(5)ꬠZ = 4. Cl, Br, I structures were refined to residuals of 0.042, 0.055, 0.039 for 4288, 2241, 4808 'observed' reflections. In all cases, the copper atom is four-coordite; for such an array, Cu-X lengths are unusually short [2.318(2), 2.459(2), 2.636(1) Š(Cl, Br, I) and Cu-N unusually long (2.14(1) Š], while (Cu-P) increase from 2.264 to 2.288 Šacross the series. The domint aspect of the complexes is thus that of XCu (PPh3)2 solvated by pyridine.
