Syntheses and Crystal Structure of Three Novel Supramolecular Halides/Pseudohalides {(DMB)[Cu2(SCN)4]}n,{(DMB)[Cu(SCN)4]}, and {(DMB)[Ag2(SCN)4]}n Directed by Dicationic Template Possessing C2-Symmetry

Three novel hybrid complexes, namely{(DMB)[Cu2(SCN)4]}n (1), {(DMB)[Cu(SCN)4]} (2), and {(DMB)[Ag2(SCN)4]}n (3), have been synthesized via the self-assembly in DMF–methanol system based on multidentate ligand DMB, {DMB = α, α′- di(3-methylimidozole-1-yl)benzene dichloride}. Single-crystal X-ray diffraction analysis shows 1 and 3 are 1D supramolecules, whereas 2 is mononuclear. Electrostatic interactions between the organic counteranions and inorganic moieties are present and do the contribution to the crystal packing. These compounds have been further characterized by IR spectroscopy and thermostability properties.
