Abstract

Abstract The reaction of Ir(CO)₂(η⁵-C₅HMe₄) with Mo₂Ir₂(μ-CO)₃(CO)₇(η⁵-C₅H₅)₂ affords a complex mixture from which three structurally-characterized products were obtained following thin-layer chromatography. Mo₃Ir₃(μ₃-O)(μ-CO)₃(CO)₈(η⁵-C₅H₅)₃ (1) is Effective Atomic Number (EAN) Rule EAN-precise and possesses an edge-bridged trigonal bipyramidal core with the face-capping oxo ligand located in a Mo₂Ir₂ butterfly cleft in the structure. Mo₄Ir₄(μ-CO)₄(CO)₉(η⁵-C₅H₅)₄ (2) possesses four electrons less than the Polyhedral Skeletal Electron Pair Theory (PSEPT)-expected count for a capped pentagonal bipyramidal cluster with the apical atoms within bonding distance. Mo₃Ir₅(μ-CO)₃(Cl)(CO)₆(η⁵-C₅H₅)₃(η⁵-C₅HMe₄) (3) possesses a tetracapped tetrahedral core and has six electrons less than the PSEPT-predicted electron count. The core geometries exhibited by clusters 2 and 3 have previously only been observed for clusters including significant group 10 and group 11 metal content.
