Tetracarbonyl-1 kappa(2)C;2 kappa(2) C-bis[3,4(eta(5))-cyclopentadieny
l]hexakis-mu- dimethylphosphito-1:3 kappa(6)O:P;2:4 kappa(6)O:P- imoly
bdenum(I)(Mo-Mo),[Mo(CO)(2){Co(C5H5)(C2H6O3P) (3)}](2), a binuclear me
tal complex of type L(2)Mo(2)(CO)4 (L is a tripod ligand), shows centr
al Mo=Mo triple bond lengths of 2.467 (1) and 2.468 (1) Angstrom in th
e two independent molecules. The structure agrees very well with that
of a related tungsten complex. The coordination of the central Mo atom
s is distorted octahedral with acute Mo-Mo-C angles. All twelve Mo-O-P
-Co fragments are synperiplanar, with Co-P bond lengths ranging from 2
.152 (2) to 2.171 (1) Angstrom.
