Three Cu(II) Complexes Constructed by Flexible bis-Imidazole and Different Anions: From 0D Architecture to 2D Layer

Three new Cu(II) complexes, Cu(1,3-bip)(Ac)(2) (I), {[Cu(H2O)(2)(1,3-bip)(2)] center dot (NO3)(2)}(n) (II), {[Cu(1,3-bip)(1,4-bdc)](2) center dot H2O center dot MeOH}(n) (III), where 1,3-bip is 1,3-bis(imidazole)propane and 1,4-bdc is terephthalic acid, have been synthesized and characterized by single crystal and powder X-ray diffraction, Fourier transform infrared spectroscopy, and elemental analysis. Single crystal X-ray diffraction reveals that the complex I shows a zero-dimensional architecture, the complex II shows a one-dimensional loop-like chain, and the complex III shows a two-dimensional (4,4) grid layer structure. In addition, the thermal stability of complexes was investigated.
