(1,4,7,10-Tetraoxacyclododecane)(trideuteroacetonitrile)lithium perchlorate

Abstract

In the title compound, [Li(C8H16O4)(CD3CN)]ClO4, the Li atom is pentacoordinate. The O atoms of the 12-crown-4 ether form the basal plane, whereas the N atom of the trideuteroacetonitrile occupies the apical position. The Li+ atom is displaced by 0.794 (6) Å toward the apical position from the plane formed by the O atoms because the Li+ atom is too large to fit in the cavity of the 12-crown-4 ether, resulting in a distorted square-pyramidal geometry about the Li+ atom.
