A theoretical study of the carbonyl complexes [M 2 (CO) 8 ] of the group 9 metals (M = Co, Rh, Ir) is presented. Three isomers were found for each metal, with the relative stabilities and energies differing from one metal to another, and two transition states corresponding to their interconversion processes were identified. The minima in the potential energy surface have been fully characterized through a vibrational [a]

## 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~COB(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
Weak antiferromagnetic exchange interactions are observed ions are separated by 8 and 10 A ˚, as determined by X-ray crystallography. Insight into the interaction pathway is in two Co II dimers of the general formula [{(triphos)Co} 2 (µdicarboxylato)](BF 4 ) 2 where the dicarboxylate is the dianion
New 1D complexes are obtained from the reaction of 1,1Јbiphenyl-2,2Ј-dicarboxylic acid (diphenic acid) with KOH and [ under hydrothermal conditions. Compounds 1 and 2 are isostructural and their structure consists of stacked helical chains of octahedral metal(II) ions. Magnetic measurements show th
