Ferratricarbollide design for molecular assemblies: complexes [9,9′-(ButHN)2-commo-2,2′-M-closo-1,7,9-(C3B8H10)-1′,7′,9′-(C3B8H10)] (where M = Fe or Ru), the first examples of double-cluster metallatricarbollides†
Abstract
The first types of double-cluster metallatricarbollides, compounds of general structure [9,9′-(ButHN)2-commo-2,2′-M-closo-1,7,9-(C3B8H10)-1′,7′,9′-(C3B8H10)] (for M = Fe or Ru), were synthesised from reactions between 7-(ButH2N)-7,8,9-C3B8H10 and FeCl2 or [RuCl2(DMSO)4] in the presence of excess NaH at high temperature; the complexes contain two amino groups conveniently attached in para-positions to the metal centres, which is a convenient feature for designed constructions of linear molecular assemblies.
