The title compound (H2tpsac) was synthesized from 6-bromosaccharin and 3,3"-bis(bromomethyl)-m-terphenyl. The ability of tpsac to serve as a tetradentate bis-bridging ligand was demonstrated by the formation of the dinuclear ruthenium(I,I) complexes [Ru2(CO)5(μ,μ- tpsac)]2, [Ru2(CO)4(μ,μ-tpsac)]n, [Ru2(CO)4(PPh3)2(μ,μ-tpsac)], and [Ru2(CO)5(PPh3)(μ,μ-tpsac)]. An X-ray crystal structure analysis of [Ru2(CO)4(PPh 3)2(μ,μ-tpsac)] showed the head-to-tail (or 1,1) arrangement of the two saccharinate coordination sites.
