The metal‐directed self‐assembly of biphenylantimony trichloride and homocarboxylic acids LH [L = 2‐CHO‐C 6 H 4 COO – ( 1 ), 2, 3‐2F‐C 6 H 4 COO – ( 2 ), 4‐CF 3 –C 6 H 4 COO – ( 3 )] provided three novel tetranuclear organoantimony(V) complexes, which were characterized by elemental analysis, FT‐IR, 1 H, and 13 C NMR spectroscopy as well as melting point, and X‐ray single crystal analysis. In the molecular structure, four hexacoordinate antimony atoms are linked into a [Sb 2 (μ‐O) 2 ] 2 (μ‐O) 2 “cage” architecture by oxo‐bridges which are terminally bridged by two carboxyl groups.
