Five organotin carboxylates based on 1,3-benzenedicarboxylic acid and 1,4-benzenedicarboxylic acid derivatives, namely (Ph3Sn) 2(4,6-L1)(H2O)2·(C 2H5OH)·4H2O (1) (4,6-L1 = 4,6-bis(4-methyl-benzoyl)isophthalic acid), (Cy3Sn) 2(4,6-L1)(DMF)2 (2), (Ph3Sn) 2(4,6-L2)(DMF)2 (3) (4,6-L2 = 4,6-dibenzoylisophthalic acid), (Ph3Sn)2(2,5-L 3)(DMF)2 (4) (2,5-L3 = 2,5-bis(4-isopropyl- benzoyl)terephthalic acid) and [(n-Bu2Sn)4(4,6-L 4)O2(OH)(OC2H5)]2· 2(C2H5OH) (5) (4,6-L4 = 4,6-bis(4-ethyl- benzoyl)isophthalic acid), have been synthesized. All the complexes have been characterized by elemental analysis, IR, 1H and 13C NMR spectroscopy and X-ray crystallography diffraction analyses. The structural analysis reveals that complexes 1-3 show similar constructions, containing binuclear triorganotin skeletons based on 1,3-benzenedicarboxylic acid derivatives. Through intermolecular hydrogen bonds and C-H?π interactions, complex 1 demonstrates as a 3D architecture while 2 as a 1D chain and 3 as a 2D network. Complex 4 is a binuclear triorganotin based on 1,4-benzenedicarboxylic acid derivative. With the intermolecular C-H?π interaction, 4 shows a 2D network structure. Complex 5 has a ladder-like octanuclear architecture composed by two Sn4O4 ladders connected by two 1,3-benzenedicarboxylic acid derivatives and form an intramolecular 24-membered macrocycle.

Six new organotin carboxylates based on 1,3-benzenedicarboxylic acid and 1,4-benzenedicarboxylic acid derivatives, namely (Ph3Sn) 2(2,5-L1)(C2H5OH)2 (1) (2,5-H2L1 = 2,5-dibenzoylterephthalic acid), (Ph 3Sn)2(2,5-L2)(C2H 5OH)2 (2) (2,5-H2L2 = 2,5-bis(4-methylbenzoyl)terephthalic acid), (Ph3Sn) 2(2,5-L3)(C2H5OH)2 (3) (2,5-H2L3 = 2,5-bis(4-ethylbenzoyl)terephthalic acid), [(n-Bu2Sn)4(4,6-L1)O2(OH)(OC 2H5)]2·2(C2H5OH) (4) (4,6- H2L1 = 4,6-dibenzoylisophthalic acid), [(n-Bu2Sn)4(4,6-L1)O2(OH)(OC 4H9)]2·2(C4H9OH) (5) and [(n-Bu2Sn)4(4,6-L2)O 2(OH)(OC2H5)]2·2(C 2H5OH) (6) (4,6-H2L2 = 4,6-bis(4-methylbenzoyl)isophthalic acid), have been synthesized. All the organotin carboxylates have been characterized by elemental analysis, IR, 1H and 13C NMR spectroscopy and X-ray crystallography diffraction analyses. The structural analysis reveals that complexes 1-3 show similar structures, containing binuclear triorganotin skeletons. The significant intermolecular O-H?O hydrogen bonds linked the complexes 1-3 to form a novel 2D network polymer with 38-member macrocycles. In complexes 4-6, two Sn4O4 ladders are connected by two 1,3-benzenedicarboxylic acid derivatives to yield ladder-like octanuclear architectures and form macrocycle with 24 atoms. In addition, the antitumor activities of complexes 1-6 have been studied.
