Abstract

The 18-electron (η⁴-C₄Me₄)Co(CO)₂TeI₂Ph compound noticeably decomposes upon prolonged storage and also unusually transforms into the 17-electron (η⁴-C₄Me₄)CoI₂(PhTeI) complex (I). The X-ray diffraction study of the molecular and crystal structures of complex I (CIF file CCDC no. 1991837) reveals interesting analogies with the molecular structures of the known metal complexes containing organotellurium halide ligands and with the crystal packing of the related one-component crystals of (η⁴-C₄Me₄)Co(СО)₂TeI₂Ph and (η⁴-C₄Me₄)Co(СО)₂I and two-component crystals of (η⁴-C₄Me₄)Co(СО)₂I–1,4-C₆H₄I₂. An analysis of the crystal packing of molecules of complex I elucidates a new supramolecular synthone I···(η⁴-C₄Me₄) determining the structural motifs of self-assembly in complex I and related compounds (η⁴-C₄Me₄)Co(CO)₂I, (η⁴-C₄Me₄)Co(CO)₂I···1,4-C₆H₄I₂, and (η⁴-C₄Me₄)Co(CO)₂TeI₂Ph. The EPR study of compound I shows that cobalt exists in the low-spin state with the total spin S = 1/2.
