A spontaneously resolved chiral molecular box: a cyclic tetranuclear ZnII complex with DPTZ (DPTZ = 3,6-di-2-pyridyl-1,2,4,5-tetrazine)

Abstract
A quantitative synthesis of a novel cyclic tetranuclear ZnII complex with 3,6-di-2-pyridyl-1,2,4,5-tetrazine (DPTZ), which was spontaneously resolved as chiral crystals, has been developed.
