A series of new five-coordinate acyl vinyl cobalt(III) complexes Co{η1-C(C{triple bond, long}CPh){double bond, long}CHPh}[C(O){single bond}C{double bond, long}C{single bond}O] L2(L = PMe3) (6-10) were prepared via formal insertion of diphenylbutadiyne into Co-H function of mer-octahedral hydrido-acyl(phenolato)-cobalt(III) complexes. The complexes are diamagnetic. One square pyramidal structure of complex 6 was confirmed by X-ray diffraction analysis. These complexes are stable in solid state. In solution, six-coordinate acyl vinyl carbonyl cobalt(III) complex 11 is approved through the reaction of complex 7 with CO and the structure of complex 11 was determined by X-ray method.
