A new 3D coordination polymer of bismuth with nicotinic acid N -oxide

Abstract

The new three-dimensional coordination polymer {[Bi(NNO) 2(NO3)]·1.5H2O}n (1, NNO- = nicotinate N-oxide) was synthesized and characterized by elemental analysis, IR and 1H-NMR spectroscopy, as well as single-crystal X-ray diffraction analysis. 1 crystallizes in the monoclinic space group C2/c. The crystal structure consists of a rectangular-shaped grid constructed with NNO linkers. Cavities of a diameter of 7.9-8.3 Å2 are filled with disordered water molecules. The thermal stability of the compound was evaluated by thermogravimetric analysis. © 2013 Farzin Marandi et al.
