Abstract

Coordination-driven self-assembly of 1,3,5-benzenetricarboxylate (tma; 1) and oxalato-bridged p-cymeneruthenium(II) building block [Ru(2)(μ-η(4)-C(2)O(4))(MeOH)(2)(η(6)-p-cymene)(2)](O(3)SCF(3))(2) (2) affords an unusual octanuclear incomplete prism [Ru(8)(η(6)-p-cymene)(8)(tma)(2)(μ-η(4)-C(2)O(4))(2)(OMe)(4)](O(3)SCF(3))(2) (3), which exhibits a remarkable shape-selective binding affinity for neutral phenolic compounds via hydrogen-bonding interactions (p-cymene = p-(i)PrC(6)H(4)Me). Such a binding was confirmed by single-crystal X-ray diffraction analysis using 1,3,5-trihydroxybenzene as an analyte.
