New supra molecular isomers with 2D 4~4 square-grid and 3D 6~5·8 frameworks in a one-pot synthesis; reversible solvent uptake and intriguing luminescence properties

摘要

Two supramolecular isomers of [Ni(4-bpd)_2(NCS)_2] (4-bpd = 1,4-bis(4-pyridyl)-2,3-diaza-1,3-butadiene) with 2D 4~4 square-grid and 3D 6~5·8 frameworks are co-crystallized in a one-pot reaction, both of which exhibit interesting luminescence properties an
