Laser-ablated Ni, Pd, and Pt atoms have been reacted with CO molecules followed by condensation in excess neon at 4 K. Besides the neutral metal carbonyl species, metal carbonyl anions [M(CO)n- (n = 1−3)] and cations [Ni(CO)n+ (n = 1−4), Pd(CO)n+ (n = 1,2), and Pt(CO)n+ (n = 1−3)] have been produced and identified. Doping with the CCl4 electron trap increases cation and decreases anion absorptions
The nickel, copper, and silver metal carbonyl chloride molecules have been prepared and isolated in solid argon by cocondensation of the species generated from 1064 nm laser ablation of metal chlorides with carbon monoxide in excess argon at 11 K. On the basis of isotopic substitution experiments and density functional theory frequency calculations, infrared absorptions at 2118.7, 2156.8, and 2184
