Intramolecular Energy Transfer in a One-Dimensional Europium Tetracyanoplatinate

The one-dimensional, polymeric compound (C15H11N3)Eu(H2O)2(NO3)(Pt(CN)4)·CH3CN (1) has been shown to display an efficient donor–acceptor intramolecular energy-transfer (IET) process where ligand donors transfer energy to the EuIII acceptor. Single-crystal X-ray diffraction has been used to investigate the structural features of this compound in order to help understand the observed IET process. Crystallographic data: 1, monoclinic, space group P21/c, a = 12.835(1) Å, b = 15.239(1) Å, c = 13.751(2) Å, β = 105.594(9)°, V = 2590.8(5) Å3, and Z = 4 (T = 290 K).
