Gh. Worth et al., REDETERMINATION OF THE STRUCTURE OF MU(6)-ACETONATO-1 2/3-KAPPA(3)C(1) - (3)C,2-KAPPA(3)C,3-KAPPA(3)C-TRIANGULO-TRICOBALT(3 CO-CO)] AT 128 K/, Acta crystallographica. Section C, Crystal structure communications, 49, 1993, pp. 1367-1369
The structure of the carbonyl-bridged dicluster compound OC[CCo3(CO)9]
2 has been redetermined from diffractometer data recorded at 128 K. Th
e broad features of the structure agree with those reported previously
[Allegra & Valle (1969). Acta Cryst. B25, 107-119] but the lengths of
the C-C bonds linking the apical carbyne C atoms of the Co3C cluster
units to the bridging keto group do not differ significantly from one
another as found in the original determination. This observation is in
keeping with the known electrochemical behaviour of the molecule.
