Silicone grease as a precursor to a pseudo crown-ether ligand: Crystal structure of (K(+)K(Me2SiO)7(+)) (HIn(CH2CMe3)3(-))4)
Abstract
The crystallization of K((HIn(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)A.
