摘要: The molecular structure of 2-methyl-4,4-diphenyl-5-phenylazo-2-thia-3-aza-4-phosphahepta-2,4-diene-6-one-2-oxide has been determined by x-ray crystallography. sulfur and phosphorus atoms exhibited distorted tetrahedral coordination. P-N P=C bond lengths are intnermediate between single double lengths. Delocalization π-electron density was observed in the flattened fragment Ph−N=N−C(=P)−C(=O)−CH3.
