Synthesis of four different antimony(III) O,O′-dialkyldithiophosphates: Characterization by 31P CP/MAS NMR, single-crystal X-ray diffraction, and adsorption at a stibnite surface (Sb2S3)

► Crystal structure determination of [Sb{S2P(O-cyclo-C6H11)2}3]·1/3 C2H5OH. ► 31P CP/MAS NMR chemical shift anisotropy parameters for [Sb{(S2P(OR)2}3] complexes are determined. ► 31P CP/MAS NMR data on dithiophosphate ligands surface adsorbed on synthetic stibnite suggest a bridging coordination.
