Silicone grease as a precursor to a pseudo crown ether ligand: crystal structure of [K+]3[K(Me2SiO)7+][InH(CH2CMe3)3–]4
Abstract
The crystallization of K[InH(CH2CMe3)3] from heptane in the presence of silicone grease led to the formation of the title compound, in which one potassium cation is surrounded by a planar cyclo-(Me2SiO)7 ligand; K+⋯ O distances range from 2.86(3) to 2.99(4)Å.
