Tetracationic cyclo-tetraphosphane [(LC)4P4]4+as triflate salt (LC= 4,5-dimethyl-1,3-diisopropyl-imidazol-2-yl) is obtained from the reduction of [LCPCl2]+with 1,4-bis(trimethylsilyl)-1,4-dihydropyrazine and represents the first salt of the cationic cyclo-phosphane series with the general formula [LnPn]n+.
