Two organo­phospho­rus pesticides: methyl para­thion and dicapthon

The structures of methyl para­thion and its 2-chloro derivative, dicapthon, are observed to have a few dissimilar features. These are notably around the C atoms to which the thio­phosphate and nitro groups are attached and those involving the phenolic O versus the -OMe groups.

Two molybdenum penta­carbonyl complexes with electro­neutral phos­phane ligands: [bis­(morpholin-4-yl)(penta­fluoro­ethyl)phosphane-κP]penta­carbonylmolybdenum(0) and penta­carbonyl[(penta­fluoro­ethyl)bis(piperidin-1-yl)phosphane-κP]molybdenum(0)

The structures of two new electro­neutral (penta­fluoro­ethyl)phosphane-ligand-containing Mo complexes are reported. Key distance and angle values are compared with those of similar complexes.
