Exploiting a substituted dihydrotriazinide as a novel bulky ligand: synthesis and crystal structure of a rubidium complex with an unprecedented tetrameric cyclic core

A metal exchange reaction between the alkoxide (BuORb)-O-t and a dihydrotriazinidolithium complex in tetrahydrofuran (thf) has yielded the first reported triazinidorubidium species, in the bis(thf) solvate of 4-n-butyl-4-tert-butyl-2,6-diphenyl-1,4-dihydro-s-triazinido-1-rubidium, which exists as a unique cyclic tetramer in the solid state having an unprecedented sixteen-membered (NCNRb)(4) ring core.
