A twofold interpenetrating three-dimensional CdII coordination framework: poly[[mu2-1,3-bis(2-methyl-1 H-imidazol-1-yl)benzene](mu-5-nitro-benzene-1,3-dicarboxylato)-cadmium(II)]

摘要

1,3-Bis(2-methyl-1H-imidazol-1-yl)benzene (1,3-BMIB) was prepared according to the previously reported procedure of Schlechte et al. (2013). All other chemicals used in the experiment were purchased from commercial sources (Sigma-Aldrich) and used without further purification. The C and H elemental analyses were performed on a Vario EL III elemental analyzer (Elementar Analysensysteme GmbH). IR spectra were recorded from KBr pellets in the range 4000-400 cm~(-1) on a Bruker VECTOR 22 spectrometer. The fluorescence spectrum was recorded on a Perkin-Elmer Fluoro Max-P spectrophotometer. The thermogravimetric analysis was performed on a Perkin-Elmer Pyris 1 TGA analyzer from 298 to 1073 K with a heating rate of 20 K min_(-1) under nitrogen (TA Instruments).
