摘　　要：Two novel heterometallic trinuclear complexes of macrocyclic oxamide [Mn（NiL）2（HBTC）H2O] （1） and [Zn（NiL）2（HBTC）H2O] （2） （NiL, H2L = 2,3-dioxo-5,6,14,15-dibenzo-1,4,8,12-tetraazacyclo-pentadeca-7,13-dien, H3BTC = 1,3,5-benzenetricarboxylic acid） have been solvothermally synthesized and structurally characterized by elemental analysis, IR spectroscopy and single-crystal X-ray diffraction. For 1, the crystals crystallize in the monoclinic system, space group P21/c with a = 11.3595（5）, b = 23.1498（11）, c = 17.2558（8） and =101.2530（10）°. For 2, the crystals crystallize in the monoclinic system, space group P21/c with a = 11.5214（8）, b = 20.6566（14）, c = 18.4126（13） and = 92.6770（10）°. The structures of 1 and 2 have oxamido-bridged trinuclear [NiⅡ2MⅡ] units and consist of two-dimensional supramolecular architectures formed by strong O–H…O intermolecular hydrogen bonds.Two novel heterometallic trinuclear complexes of macrocyclic oxamide [Mn（NiL）2（HBTC）H2O] （1） and [Zn（NiL）2（HBTC）H2O] （2） （NiL, H2L = 2,3-dioxo-5,6,14,15-dibenzo-1,4,8,12-tetraazacyclo-pentadeca-7,13-dien, H3BTC = 1,3,5-benzenetricarboxylic acid） have been solvothermally synthesized and structurally characterized by elemental analysis, IR spectroscopy and single-crystal X-ray diffraction.
