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 [space group P21, a=8.0770(10) Å, b=7.6481(10) Å, c=8.0859(10) Å, β = 116.825(2)o, Z=2]. It has a unique crystal structure buildup of 1D chains of InO7 pentagonal bipyramids running along [010]. The compound has been characterized by 115In NMR and NQR spectroscopy. Rather high values of quadrupole constant (CQ=182(1) MHz) and asymmetry parameter (η=0.38) extracted from numerical simulation of experimental 115In NMR and NQR spectra agree with large distortion and asymmetric coordination of In3+ in the crystal structure of In(CH3COO)3.
