Near-infrared luminescent and magnetic cyano-bridged coordination polymers Nd(phen)(n)(DMF)(m)[M(CN)(8)] (M = Mo, W)

Abstract

New cyano-bridged coordination polymers [Nd(phen)(2)(DMF)(2)(H(2)O)Mo(CN)(8)] center dot 2H(2)O (1) and [Nd(phen)(DMF)(5)M(CN)(8)] center dot xH(2)O [M = Mo (2), W (3); phen = 1,10-phenanthroline] have one-dimensional structures with variable number of phenanthroline ligands. Compounds exhibit photoluminescence in the near-infrared region and ferromagnetic Nd(3+)-M(5+) interactions.
