The crystal structure of tetragonal P4O6S4

The crystals of P4O6S4 are tetragonal with space group . The unit cell with dimensions a = 9.065 and c = 13.55 A contains four molecules with symmetry (Td) at positions 000, 00 ½, ½ ½ ½ and ½ ½ 0. The structure was solved by vector analysis and refined by the least-squares method using CuKα reflexions (eye-estimated and partly photometered data). The average PO and PS distances are 1.61 and 1.86 A. The shape of the molecule and the packing are compared with those of analogous molecules.
