New supramolecular isomers with 2D 44 square-grid and 3D 65·8 frameworks in a one-pot synthesis; reversible solvent uptake and intriguing luminescence properties.

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 44 square-grid and 3D 65·8 frameworks are co-crystallized in a one-pot reaction, both of which exhibit interesting luminescence properties and reversible adsorption–desorption with respect to guest solvents.
