A metal exchange reaction between the alkoxide ButORb 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.
