摘要:
Organoantimony(III) sulfide (1) containing the NCN chelating ligand L [L = 2,6-(CH2NMe2)(2)C6H3] displays unusual dual behavior, being dimeric (LSbS)(2), with the central Sb2S2 core, in the solid state but monomeric in solution. Sulfide 1 reacts with elemental S to give the unprecedented cyclic bis(pentasulfide) LSb(mu-S-5)(2)SbL (2) with the central 12-membered ring Sb2S10.
