Crystal structure of lignocaine tetrachloroferrate (III) complex

The crystal structure of lignocaine tetrachloroferrate(III) complex, FeCl14H22N2OCl4, has been determined by X-ray diffraction using CuKalpha radiation. The compound crystallizes in triclinic space group P1BAR with unit cell parameters a = 8.7151(2) angstrom, b = 10.147(2) angstrom, c = 12.215(3) angstrom, alpha = 107.19(2)-degrees, beta = 106.29(2)-degrees, gamma = 92.69(2)-degrees with V = 980.5(4) angstrom3, Z = 2, D(m) = 1.441 Mg . m-3, D(c) = 1.463 Mg. M-3, mu = 22.75 mm-1. The structure was solved using 2728 reflections I > 2.5sigma(I)] out of 3230 reflections by MULTAN. The final residuals are R(f) = 0.085 (R(w) = 0.106)
