Define a search for molybdenum carbon monoxide complexes

•	Start ConQuest and click on the Draw button on the left-hand side of the interface. This launches the sketcher window.

•	The carbon C atom will be selected by default. Introduce a C atom into the sketcher window by left-clicking with the mouse in the middle of the window.

•

We now need to draw an oxygen atom which is triply bonded to the C. In the atom list at the bottom of the sketcher, pick O, then move along to the Bond: pull down menu and select Triple. Go to the C atom in the sketcher. Left-click and keeping the left mouse button depressed, move the mouse to the right until you see a triple bond appear. Release the left mouse button, and an O atom will be drawn bonded to the C.

•

Now bond a molybdenum atom to the C atom using a single bond by clicking on the More button at the bottom of the sketcher and selecting Other Elements.... Pick Mo from the resultant periodic table, then click OK. Now change the bond style to Single using the Bond: pull down menu at the bottom of the sketcher window. Left-click on the C atom in the sketcher and keeping the mouse button depressed, move to the left until a single bond appears, at which point release the mouse button.

•	The resultant substructure will look like the following:
