The previously reported (neocuproine)CdFe(CO)4 has been found to crystallize as either a dimer or a trimer depending on the procedure used. These species exist as nearly planar four- and six-membered rings composed of alternating cadmium and iron atoms. The trimeric form is reasonably similar to its 2,2′-bipyridyl analogue, while the dimeric form had not been observed previously for a CdFe(CO)4 complex. The space group for the dimeric isomer is C2/c, with (3), (2), (2)  Å, and (11)°, while for the trimeric isomer the space group is P , with (1), (1), (2)  Å, (3)°, (4)°, and (5)°.
