Side-on bonded nitrosobenzene bridging two metal atoms, in a binuclear cyclopentadienyl cobalt complex: crystal structure of [{Co(cp)}2(µ-PhNO)2]

Abstract

Nitrosobenzene reacts with [Co(cp)(C₂H₄)₂](cp =η⁵-C₅H₅) producing in high yield (ca. 82%) a binuclear complex having two cobalt atoms bridged by two nitrogen atoms of nitrosobenzene side-on bonded to each cobalt, [{Co(cp)}₂(µ-PhNO)₂]. The structure of this complex was determined by X-ray diffraction analysis: orthorhombic, space group Pbca, with a= 12.937(9), b= 19.509(6), c= 7.714(6)Å, Z= 4, and R= 0.031.
