The crystallization of KInH(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.
Churchill et al. (1993) studied this question.
