[V(NCBH3)(2)(thf)(4)], the first cyanohydroborato complex of an early trans
ition metal, has been generated in the system [V(CO)(6)](-) /I-2/ tolane/Na
[NCBH3] in THF. The crystal structure reveals an ideal trans configuration
(point group D-2h) with about linear CNBH3- units, and without intermolecul
ar (hydrogen bonding) interactions. (C) 2000 Elsevier Science S.A. All righ
