In (2,7,9,14-tetramethyl-1,4,8,11-tetraazacyclotetradecane-κ4N)bis(thiocyanato- N)nickel(II) (2,5,9,12-tetramethyl-1,4,8,11-tetraazacyclotetradecane-κ4N)bis(thiocyanato-N)nickel(II) diacetonitrile solvate, [NiL1(NCS)2][NiL2(NCS)2]·2CH3CN, where L1 and L2 (C14H32N4) are isomeric tetraazacyclotetradecane ligands, each of the co-crystallized complexes has an NiN4 square plane involving the four N atoms of the secondary amine. In each of the two isomeric complexes, the two thiocyanate ligands coordinate axially through their N atoms.
