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 groupP21/c with a = 11.3595(5), b = 23.1498(11), c = 17.2558(8) Å andb =101.2530(10)°. For 2, the crystals crystallize in the monoclinic system, space groupP21/c with a = 11.5214(8), b = 20.6566(14), c = 18.4126(13) Å and b =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.
