Zusammenfassung:	Cephem derivs. of formula (I) and their pharmaceutically acceptable salts are new. R1 = opt. protected amino; R2 = opt. substd. lower alkyl; R3 = COO(-) or opt. protected carboxy; R4 = lower alkyl substd. by opt. protected hydroxy; R5 = opt. protected amino; R6 = H or lower alkyl; X = anion; n = 0-1; provided that when (1) R3 = COO(-) then n = O; and (2) R3 = opt. protected carboxy then n = 1; lower = 1-6C.
