Abstract

An open capsule-type octanuclear heterometallic sulfide cluster without an intramolecular inversion center [Ru(η6-C6Me 6){P(OMe)3}{MoO(μ3-S)3}(Cul) 2]2 (5) has been synthesized for the first time by stepwise connection of three mononuclear building blocks, i.e., (i) [RuCl 26-C6Me6){P(OMe)3}] (1a) as an octahedral terminal building block to control the direction of cluster expansion, (ii) [MoOS3]2- as a tetrahedral polydentate building block owing to the strong coordination ability of the S atoms, and (iii) a Cul building block to form a trigonal planar (μ-S) 2Cul unit or to form a linkage unit of two incomplete cubane-type octanuclear frameworks. The stepwise connection was made in the following order: [RuCl26-C6Me6){P(OMe) 3}] (1a, mononuclear) → [Ru(η6-C 6Me6){P(OMe)3}{MoOS(μ2-S) 2}] (2a, dinuclear) → [Ru(η6-C6Me 6){P(OMe)3}{MoO-(μ2-S)23-S)}Cul] (3a, butterfly-type trinuclear) → [Ru(η 6-C6Me6){P(OMe)3} {MoO(μ3-S)3}(Cul)2]2 (5). When P(OMe)3 was replaced by P(OEt)3, which is more bulky than P(OMe)3, in the starting ruthenium building block [RuCl 26-C6Me6){P(OEt)3}] (1b, mononuclear), only the tetranuclear incomplete single cubane cluster [Ru(η6-C6Me6){P(OEt)3} {MoO(μ3-S)3}(Cul)2] (6) was generated, owing to the steric effect of P(OEt)3.
