Metal Complexes with the N-Heterocyclic Ligand: Synthesis, Structures, and Thermal Decomposition

Аннотация

The heterometallic nickel and iron chalcogenide complexes, (η⁵-C₅H₅)Ni(MeIm)S(µ₂-SⁿPr)Mn(CO)₂(η⁵-C₅H₅) (I) and (η⁵-C₅H₅)Fe(MeIm)(CO)(µ₂-SPh)Mn(CO)₂(η⁵-C₅H₅) (II), and the cobalt nitrosyl complex (MeIm)Co(NO)₂I (IIIa, IIIb) (CIF files CCDC nos. 1911962 (I), 1911963 (II), 1911964 (IIIa), and 1911965 (IIIb)) are synthesized and structurally characterized. According to the data of thermogravimetry and differential scanning calorimetry (TG–DSC), the organic moiety of the molecule of complex I is lost to form the NiMnS residue, whereas ferrocene is formed upon the thermal decomposition of complex II.
