Tetrakis(mu-triisopropylsilanethiolato)-1:2kappa4S:S;2:3kappa4S:S-bis(triisopropylsilanethiolato)-1kappaS,3kappaS-trizinc(II).
The title compound, [Zn(3)(C(9)H(21)SiS)(6)] or [((i)Pr(3)SiS)Zn(mu-SSi(i)Pr(3))(2)Zn(mu-SSi(i)Pr(3))(2)Zn(SSi(i)Pr(3))], is the first structurally characterized homoleptic silanethiolate complex of zinc. A near-linear arrangement of three Zn(II) ions is observed, the metals at the ends being three-coordinate with one terminally bound silanethiolate ligand. The central Zn(II) ion is four-coordinate and tetrahedral, with two bridging silanethiolate ligands joining it to each of the two peripheral Zn(II) ions. The nonbonding intermetallic distances are 3.1344 (11) and 3.2288 (12) A, while the Zn...Zn...Zn angle is 172.34 (2) degrees. A trimetallic silanethiolate species of this type has not been previously identified by X-ray crystallography for any element.
