Reaction of zero-valent cobalt and iron species with seven-atom carbaboranes; molecular structures of [4-(Et3P)-1,7-Me2-µ4,8-{Co(H)-(PEt3)2-µ(H)-µ(PEt2)}-1,4-7-CCoCB5H4] and [4,4,4-(ButNC)3-1,7-Me21-1,4,7-CFeCB5H5]
Abstract
Reaction of closo-2,4-Me2-2,4-C2B2H5 with [Co(PEt3)4] affords a novel dicobalthydrido-complex containing a phosphido-bridge, whereas [Fe(CNBut)5] reacts to form a mononuclear 8-atom cage, in which the iron atom has a cluster connectivity of five.
