title: [η-(Phenyl-ethyn-yl)cyclo-penta-dien-yl](η-tetra-phenyl-cyclo-butadiene)cobalt(I).
abstract: In the title compound, [Co(C(13)H(9))(C(28)H(20))], the Co atom is sandwiched between cyclo-penta-dienyl and cyclo-butadienyl rings that are inclined at a dihedral angle of 2.6 (3)°. The four phenyl rings are tilted with respect to the cyclo-butadienyl plane so that the C(4)Ph(4) unit constitutes a four-bladed propeller. The phenyl ring of the phenyl-alkyne substituent is inclined to the cyclo-penta-dienyl ring at an angle of 34.92 (18)°. The crystal structure is stabilized solely by C-H⋯π inter-actions which generate a three-dimensional network.
