Polymorphism and reactivity of [Ni(pyridine)4(NCS)2]: Two new supramolecular isomers and one macro-ionic derivative image

Solvothermal treatment of [Ni(pyridine)4(NCS)2] in the presence of 4,5-imidazoledicarboxylic acid allows the isolation of two new polymorphs depending on solvents (CH3CN or CH3CN/CH3OH). Furthermore, one unusual conductive macro-ionic complex image is obtained when the reaction is carried out in CH3OH, providing a new insight into polymorphism and reactivity of [Ni(pyridine)4(NCS)2].
