The samples of nominal composition Bi{sub 1.6}Pb{sub 0.4}Sr{sub 2}Ca{sub 3}Cu{sub 4}O{sub 12{minus}x}F{sub x} consist of {alpha},{beta},{gamma}, and {delta}-modifications of phase 2234. The authors observed the superconducting transition in the temperature region 110--132 K for samples z {<=} 0.25. The possible model of creating superconducting state in Bi{sub 1.6}Pb{sub 0.4}Sr{sub 2}Ca{sub 3}Cu{sub 4}O{sub 12{minus}x}F{sub x} samples is proposed.
