Triply-bridging bis-hydridborylene) and bis-borylene species of groups 6, 8 and 9 transition metals are reported. Mild thermolysis of [Fe2 (CO)9 ] with an in situ produced intermediate, generated from the low-temperature reaction of [Cp*WCl4 ] (Cp*=η5 -C5 Me5 ) and [LiBH4 ⋅THF] afforded triply-bridging bis-hydridborylene), [(μ3 -BH)2 H2 Cp*W(CO)2 2 Fe(CO)2 ] (1) and bis-borylene, [(μ3 -BH)2 Cp*W(CO)2 2 Fe(CO)3 ] (2). The chemical bonding analyses of 1 show that the B-H interactions in bis-hydrido (borylene) species is stronger as
