In(CH3COO)3: the First Example of Group 13 Elements Triacetate with an Infinite Chain Crystal Structure
Polyhedron(2019)
Abstract
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).
