Polyhedral ruthenaborane chemistry.Approaches to encapsulated boron cores.The isolation and characterisation of the partially encapsulated isocloso 10-vertex {RuB_9} cluster compound [(PPh_3)RuB_9H_9{RuCl_2(PPh_3)_2}_2]

摘要

[RuCl_2(Ph_3)_2] with [arachno-R_9H_(14)]~- gives [(PPh_3)RuB_9H_9{RuCl_2(PPh_3)_2}_2],which has an isocloso 10-vertex {RuB_9} core geometry that is partially encapsulated by exo-polyhedral {RuCl_2(PPh_3)_2} units that cap {RuB_2} triangular faces with one {RuClRu} and two {RuHB} bridges each.The structure engenders focus on the several new compound classes emerging in polyhedral boron-containing cluster chemistry.
