[η5-(Phenylethynyl)cyclopentadienyl](η4-tetraphenylcyclobutadiene)cobalt(I)

Abstract

In the title compound, [Co(C13H9)(C28H20)], the Co atom is sandwiched between cyclopentadienyl and cyclobutadienyl rings that are inclined at a dihedral angle of 2.6 (3)°. The four phenyl rings are tilted with respect to the cyclobutadienyl plane so that the C4Ph4 unit constitutes a four-bladed propeller. The phenyl ring of the phenyl-alkyne substituent is inclined to the cyclopentadienyl ring at an angle of 34.92 (18)°. The crystal structure is stabilized solely by C—H...π interactions which generate a three-dimensional network.
