By reaction of [(π-H₅H₅)(CO)₂Mn≡C-C₆H₅]BCl₄ with NaRe(CO)₅ a new type of complex is obtained. It crystallizes in the monoclinic space group P2₁/c, Z = 4, a - 1115(1), b= 1464(1), c= 1657(2) pm, β= 136.79(8)°. Structure determination reveals a binuclear complex, the Mn-Re bond (281.7(3) pm) of which is bridged by the a-carbon atom of a phenylketenyl group (Mn-C 221(3), Re-C 224(3) pm) and semi-bridged by a CO group (Mn-C 187(4), Re-C 254(4), Mn-C-0 160(3)°).
