A solvothermally in situ generated mixed-ligand approach for NLO-active metal-organic framework materials

The synthesis and crystal structures of two new NLO-active coordination polymers, [Zn(2-pc)(4-pc)] and [Cd(2-pc)(4-pc)(H2O)]center dot N2H4 (2-pc = 2-pyridine carboxylate, 4-pc = 4-pyridine carboxylate), bridged by in situ generated mixed ligands under solvothermal treatment is described.
