Molybdenum complexes trigonal bipyramid

We noted earlier that two collinear bonds to metal atoms are formed by 0 in some finite ions and molecules. Examples include compounds of both transition and non-transition metals (Table 11.5). In all cases the short M-0 bonds indicate multiple-bond character though there are still shorter bonds to terminal 0 atoms in some of the molybdenum complexes. Details of some of these complexes are given at (a)-(c). Note the trigonal bipyramidal coordination of A1 in (a).
