Borane carbonyl is the inorganic compound with the formula H₃BCO. This colorless gas is the adduct of borane and carbon monoxide. It is usually prepared by combining borane-ether complexes and CO. The compound is mainly of theoretical and pedagogical interest.^[1] It reacts with aqueous base to give Boranocarbonate H₃BCO₂²⁻.^[2] Bond distances are B-C, 1.529; C-O, 1.140; 1.194 Å. The H-B-H angle is 113.7°. The CO vibrational band is at 2165 cm⁻¹, 22 cm⁻¹ higher than that of free CO.^[3]
