Reversible and Massive Structural Transformation in Meltable Cyanido-bridged Coordination Polymer Crystals.

ABSTRACT: Cyanido (CN^-)-bridged coordination polymers (CP) have been extensively studied as molecular-based functional materials. However, synthesizing 3D compounds composed only of metal ions and CN^--without bulky organic groups-and that melt before decomposing remains a considerable challenge. This difficulty arises because CN^- strongly interconnect metal ions, forming rigid, dense frameworks with high melting points. In this study, we successfully synthesized a melting composite consisting of 3D KCd[Cu(CN)₂]₃ and 2D K₂Cu₃(CN)₅ by dehydrating K₂Cd(H₂O)Cu₄(CN)₈·1.5H₂O. Remarkably, nanodomains of these two compounds coexisted within single particles, allowing
