Treatment of M[Co(C2B9H11)2], M = Na or K, with [2.2.2]cryptand and 5,7,12,14-tetramethyldibenzo[b,i]-1,4,8,11-tetraazacyclotetradeci nenickel(II) results in a 1∶1∶1 complex, assembled with the cobalticarborane anion snugly residing in the phenyl lined face of the Ni(II) macrocycle through C–H…N and C–H⋯π interactions, with the ensuing [M⊂[2.2.2]cryptand]+ supercation residing in the smaller methyl faced cavity of the macrocycle.
