Abstract
Six molecular squares were obtained by reacting the singly metal-metal-bond ed complex [Rh-2(cis-DAniF)(2)(CH3CNeq)(4)(CH3CNax)(2)](BF4)(2) (DAniF=N,N' -di-p-anisylformamidinate), and (Et4N+)(2)(Carb(2-)) where Carb(2-) represe nts the dicarboxylate anion bicyclo[1.1.1]pentane-1,3-dicarboxylate, 1; tet rafluoroterephthalate, 2; 1,4-cubanedicarboxylate, 3; terephthalate, 4; fum arate, 5; trans-1,4-cyclohexanedicarboxylate, 6; these squares stack in the crystal forming square channels capable of accommodating solvent molecules and the NMR spectra are consistent with the presence of highly symmetrical structures even in solution.
