摘要：
The asymmetric unit of the title compound, [Co(C24H30N2P2)(CO)(3)][Co(CO)(4)]-0.25C(7)H(8), consists of two crystallographically independent cations with similar conformations, two anions, and one-half of a toluene molecule disordered about an inversion centre. In the cations, a Co/P/N/P four-membered slightly bent metallacycle is the key structural element. The pendant NH group is not coordinated to the Co-I atom, which displays a distorted trigonal-bipyramidal coordination geometry. Weak interionic hydrogen bonds are observed between the NH groups and a carbonyl group of the tetrahedral [Co(CO)(4)](-) anions.
