Structural variations in bimetallic sodium–magnesium and sodium–zinc ketimides, and a sodium–zinc alkide–alkoxide–amide: connections to ring-stacking, ring-laddering, and inverse crown concepts†
Abstract
The first sodium–magnesium and sodium–zinc ketimido complexes display contrasting inverse crown ring and pseudo-cubane structures respectively, while a sodium–zinc heterotrianionic alkide–alkoxide–
