The antimony containing cage compound, P4Sb2C4But4, was treated with an excess of [M(CO)5(THF )], M 4;= 4;Cr, Mo or W, to produce the 2∶1 adduct complexes, [{M(CO)5}2(η1∶η1-P4Sb2C4But4)], which X-ray crystallographic studies have shown to contain one M(CO)5 fragment co-ordinated to an unsaturated phosphorus centre and one co-ordinated to an antimony centre. In contrast, its reaction with an excess of [Fe2(CO)9] produced [{Fe(CO)4}2{Fe(CO)3(η3∶η1-P4Sb2C4But4)}], which is probably formed by the insertion of an Fe(CO)3 fragment into an Sb–P bond of the cage. Its crystal structure confirms that it contains two η1-co-ordinated Fe(CO)4 groups and a 1,3-diphosphaallyl fragment η3 co-ordinated to an Fe(CO)3 moiety. |
