Abstract

The antimony aminoalkoxide and aminothiolates Sb(ECH 2CH 2NMe 2) 3 [E = O (1), S (2)] were synthesized and their ability to form adducts with other metal moieties investigated. Compound 1 forms 1:1 adducts with NiI 2 (3) and M(acac) 2 [M = Cd (4), Ni (5)], while 2 undergoes ligand exchange with AlMe 3 to afford Me 2AlSCH 2CH 2NMe 2 (6). The structures of 2-4 and 6 were determined. Compound 2 incorporates three S, N-chelating ligands though the interaction with nitrogen is weaker than in analogous alkoxide complexes. Product 3 reveals one iodine has migrated from nickel to antimony, and all three alkoxide ligands bridge the two metals through μ 2-O atoms. In contrast, in 4, only one alkoxide links the antimony and cadmium. Compound 6 adopts the same structure, a chelating S,N ligand generating a tetrahedral center at aluminum, as known tBu 2AlSCH 2CH 2NR 2 species (R = Me, Et).
