Assembly of noncentrosymmetric coordination polymers by the integration of acentric Ba(ii)/Sr(ii) and Li(i) coordination polyhedra†
Abstract
Presented is a new feasible strategy to construct heterometallic coordination polymers with noncentrosymmetric structures, through the integration of acentric [MOxNy] (M = Ba, Sr; x + y = 8–10) polyhedra and [LiOxN4−x] tetrahedra via bridging organic ligands.
