| Abstract: | Three complexes based on methyl-pyrimidine-2-thione, 5-methyl-5,8,9,10-tetrahydro-5,9methanopyrimido[5,4-e][1, 3]diazocine-2,7-dithiol (mtmdd) (1), and Ni(mpymt)2(N2H4)·H2O (2) and [Cd(mpymt)2]∞ (3) have been synthesized under hydrothermal conditions and characterized by elemental analysis, infrared (IR) spectroscopy, thermal gravimetric analysis, powder X-ray diffraction, and single-crystal X-ray diffraction. Structural analysis reveals that 1 is generated from an in situ translation of mpymt. In 2, two Ni(mpymt)2 fragments were joined into a dinuclear complex by two NH2–NH2 molecules. Compound 3 is a two-dimensional Cd coordination polymer constructed by Cd2(mpymt)2 SBUs and mpymt anions. Variable-temperature magnetic susceptibility measurement of 2 revealed strong antiferromagnetic interactions between nickel magnetic centers. The fluorescent properties of 1 and 3 were investigated in the solid state. |
