New metalloligands [M(SC{O}Ph)4]-:: Synthesis and characterization of polymeric [A(MeCN)x{M(SC{O}Ph)4}] compounds (A = Li, Na and K; M = Ga and In; x=0-2)

Exploiting the ability of the [M(SC{O}Ph)(4)](-) anion to behave like an anionic metalloligand, we have synthesized [Li{Ga(SC{O}Ph)(4)}] (1), [Li{In(SC{O}Ph)(4)}] (2), [Na{Ga(SC{O}Ph)(4)}] (3), [Na(MeCN){In(SC{O}Ph)(4)}] (4), [K{Ga(SC{O}Ph)(4)}] (5), and [K(MeCN)(2){In(SC{O}Ph)(4)}] (6) by reacting MX3 and PhC{O}S(-)A(+) (M = Ga(III) and In(III); X = Cl- and NO3-; and A = Li(I), Na(I), and K(I)) in the molar ratio 1:4. The structures of 2, 4, and 6 determined by X-ray crystallography indicate that they have a one-dimensional coordination polymeric structure, and structural variations may be attributed to the change in the alkali metal ion from Li(l) to Na(l) to K(l).
