A pseudosymmetric triclinic modification of triphenyltin isopropylxanthate

S. W. Ng and A. D. Rae

Synopsis: All three independent molecules in the triclinic modification of (O-isopropyl dithiocarbonato-S)triphenyltin show tetrahedral coordination at their Sn atoms. Bond dimensions involving the Sn atoms are similar to those found in the monoclinic modification of the same compound. Two of the independent molecules are related by a pseudo-translation allowing a stacking fault that reduces the intensities of h + k odd reflections.

Triclinic polymorphs of triphenylphosphine and triphenylphosphine sulfide

B. Ziemer, A. Rabis and H.-U. Steinberger

Synopsis: New triclinic polymorphs of triphenylphosphine, C₁₈H₁₅P, (I), and triphenylphosphine sulfide, C₁₈H₁₅PS, (II), were crystallized. For the structure of (I), it is obvious that the highest peaks in the final difference electron-density map are located at the `lone-pair regions' of P atoms. We have observed this effect in two further phosphorous-containing structures.
