Abstract

The complex (A), 3,5,6-trichloro-2-pyridinol-piperazine. C9Hd2N30C1,, crystallizes in the monoclinic space group P21/1z with the parameters n = 8.9134) A. b = 7.062(3) A. c = 19.039(5) A, f3 = 102.79(3)", V= 1168.9(8) A3, Z=4. The structure was solved by direct methods using SHELXS-86 (Sheldrick. 1990) and refined using SHELXL-93 (Sheldrick. 1993). The final residual factor is R1 = 0.0662 for 1273 reflections with I > 20(0. The structure has intermolecular hydrogen bonds. The molecules which are stacked in layers are interconnected through the hydrogen bonds. The complex B, 3,5,6-trichloro-2-pyridinol-piperdineC,, ,H,,N,OCI,. crystallizes in the monoclinic space group PZ,/r with the parameters (I = 12.514(4) A, b = 22.464(2) A, c = 13.765(3) A, p =98.02(2)", V=3831.9(2) A3, Z = 12. The structure was solved by direct methods using SHELXS-86 and refined using SHELXL-93. The fmal residual factor is R1 = 0.072 for 2662 reflections with I > 20(I). The structure has both intra and intermolecular hydrogen bonds.
