Popis: Bis(tetraphenylantimony) malonate was synthesized by the reaction of tetraphenylantimony bromide with silver malonate (the molar ratio was 2:1) in toluene. According to the X-ray diffraction data, the tridentate carboxylate ligand is a chelate. The coordination number of the Sb(1) atom involved in a contact with the carbonyl oxygen atom increases to six (Sb(1)—O(1), 2.199(7) A; Sb(1)—O(3), 2.362(7) A). Another antimony atom remains five-coordinate (Sb(2)—O(4), 2.304(7) A). The antimony atoms Sb(1) and Sb(2) have distorted octahedral and trigonal-bipyramidal coordination geometry, respectively.
