In(CH3COO)3: the First Example of Group 13 Elements Triacetate with an Infinite Chain Crystal Structure

Single crystals of In(CH3COO)(3) have been prepared by dissolution of basic indium carbonate In(OH)CO3 in a mixture of anhydrous acetic acid and acetic anhydride. The crystal structure of In(CH3COO)(3) has been solved and refined for the first time using single crystal X-ray diffraction data. It has a unique crystal structure buildup of 1D chains of InO7 pentagonal bipyramids running along [0 1 0]. The compound has been characterized by In-115 NMR and NQR spectroscopy. Rather high values of quadrupole constant (C-Q = 182(1) MHz) and asymmetry parameter (eta = 0.38) extracted from numerical simulation of experimental In-115 NMR and NQR spectra agree with large distortion and asymmetric coordination of In3+ in the crystal structure of In(CH3COO)(3).
