✦ Synopsis

The electrostatic complex of Co+ with a single CO2 molecule is studied by optical excitation of a 3d74s-3d8 transition centered on the metal ion. Excited-state vibrational information is used to characterize the diabatic molecular potential in terms of spectroscopic constants. Two vibrational frequencies and five anharmonicity constants characterize the forces of complexation, all of which have been determined experimentally. Analysis of the rotational contours indicates the complex is linear in its ground electronic state with a Co+-C separation of 3.30 8, (the smaller Co+-0 distance: 2.14 A) in the zero-point level of the complex.

## Abstract The reaction of [Co~2~(CO)~8~] with (CF~3~)~3~BCO in hexane leads to the Lewis acid–base adduct [Co~2~(CO)~7~COB(CF~3~)~3~] in high yield. When the reaction is performed in anhydrous HF solution [Co(CO)~5~][(CF~3~)~3~BF] is isolated. The product contains the first example of a homolept
