Abstract

Treatment of the cisoid-capped complex [Pt₄(μ-OCOCH₃)₆(κ⁴-N₄-DAr′Bp)] (2a), which was obtained from the reaction of [Pt₄(μ-OCOCH₃)₈] (1) with Na₂D^tBuPhBp (D^tBuPhBp = 1,3-bis(para-tert-butylphenylbenzamidinate)propane), with an equimolar amount of 1,1′-ferrocenedicarboxylic acid undergoes a stereoselective self-assembly to afford an indented-quadrangle tetramer [Pt₄(μ-OCOCH₃)₄(κ⁴-N₄-D^tBuPhBp){Fe(C₅H₄COO)₂}]₄ (4) as a single diastereomer.
