The crystal structures of the tetra(2-thienyl) derivatives of germanium, tin and lead

Abstract

The crystal structures of the tetra(2-thienyl) derivatives of Ge, Sn and Pb have been determined from three-dimensional single-crystal X-ray diffraction data. All three compounds crystallize in space group P42~c and have crystallographically imposed 3, symmetry. The thienyl rings in each structure exhibit twofold orientational disorder, and structure refinement by rigid-body full-matrix least-squares methods yielded conventional R values of 0-095, 0.069 and 0-055 for (C4H3S)4Ge, (C4H3S)4Sn and (C4H3S)4Pb respectively.
