Syntheses, structures and luminescence of three copper(I) cyanide coordination polymers incorporating flexible N-donor ligands

Three copper(I) cyanide coordination polymers were constructed based on two flexible N-heterocyclic ligands. [Cu8(CN)8(btmb)2]n (1) is a 2D double-layered network containing eight distinct Cu(I) centers and eight μ2-cyanides. Complex 2 shows a ladder-like chain structure, while complex 3 exhibits a 2D wave-like network. These Cu(I) complexes are stable up to 270-300 °C and emit blue luminescence.208
