Two dechlorinated products (B) and (D), formed in the reaction between endrin (C12H8Cl6O) and vanadium(II) for the purpose of confirmation of identity, are shown by single-crystal X-ray structure determination to be isomers of the title compound, C12H9Cl5O. Crystals of both are monoclinic, P21/c. For isomer (B), a 7.432(8), b 12.76(1), c 14.55(2) � , β 108.32(9)�, Z=4; R was 0.038 for 2594 observed reflections. For isomer (D), a 9.037(4), b 12.004(4), c 14.436(6) � , β 124.91(2)°, Z= 4; R was 0.041 for 1826 reflections. The geometries of the two isomers are compared.

Complexes [ XCu ( py )(PPh3)2], X = Cl, Br, I, py = pyridine, have been synthesized and characterized by single-crystal X-ray structure determination. Chloride and iodide derivatives have similar cells [ isomorphous (?) but not isostructural ], triclinic, pi, a = 19.5 A, b = 10.5, c = 9.6 � , α ≈ 66, β ≈ 86, γ ≈ 83�, Z = 2; the bromide is monoclinic, Cc, a 13.568(9), b 15.760(12), c 16.545(8) � , β 95.65(5)�, Z = 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-coordinate; for such an array, Cu-X lengths are unusually short [2.318(2), 2.459(2), 2.636(1) � (Cl, Br, I) and Cu-N unusually long (2.14(1) � ], while (Cu-P) increase from 2.264 to 2.288 � across the series. The dominant aspect of the complexes is thus that of XCu (PPh3)2 solvated by pyridine.

Structure Determinations

Single-crystal room-temperature X-ray structure determinations of the title compounds have been carried out. The two compounds are isomorphous, and isomorphous with the previously determined iodide analogue, being monoclinic, P 21/c, a ≈ 10.0, b ≈ 14.9, c ≈ 7.8 Ǻ, β ≈ 92°, Z = 4 formula units; residuals were 0.037, 0.036 for 2197, 1654 'observed' reflections for X = Cl , Br respectively. As in the iodide, the complexes are infinite polymers, with successive bismuth atoms bridged by the two halides and one sulfur atom of the ligand , which also chelates each bismuth. The structure determination of C5H5NCONEt2]2 [Cl5Bi(NC5H5)], isostructural with its thiocarbamoyl analogue, is also recorded.

The isolation and single-crystal X-ray structure determination of the title compound, [(phen)2Pb(NCS)(O2NO)] is described; crystals are triclinic, P1, a 15.554(7), b 9-670(4), c 8.429(3) α 72.53(3), β 81.90(3), γ 72.88(3)� Z = 2, yielding R 0.052 for 3405 independent 'observed' reflections. The lead atom is seven-coordinate [Pb-N 2.49(1)-2.60(1) (phen), 2.89(1) (NCS); Pb-O 2.75(1), 2.89(1) �] with a large vacancy in the coordination sphere, possibly indicative of a stereochemically active lone pair.
