How to Draw Structures with Coordinate Bonds

You can draw coordinate bonds for organometallic compounds in Mbook!

Structures with π coordination (uncharged)

We would like to show a couple of examples of uncharged structures:

a)  Dichloro(ethyldiamine)platinum(II):

Use Mbook molecular editor to start building the structure and click on the ‘Coordinate’ button to draw a bond between the N atoms and the Pt atom. The structure drawn will have the correct molecular formula and weight.

b)  Bis(benzene)chromium(0)

As the example above showed, start building the structure, select one of the rings and the metal atom, and click on the ‘Coordinate’ button to draw a bond between them. Now select the metal and the other ring and click on the “coordinate” button again. As a result, the second coordinate bond is added and the structure obtaining the expected molecular formula and weight.

Structures with π coordination (charged)

a)  Bis(cyclopentadienyl)cobalt(II)

Use Mbook molecular editor to start building the structure. Select one of the rings and the metal and click on “Coordinate”, a new bond is created between the ring and the metal. Now select the metal and the other ring and click on the “coordinate” button again. As a result, the second coordinate bond is added and the structure obtaining the expected molecular formula and weight.

b)  Allyl chloro[1,3-bis(2,6-diisopropylphenyl) imidazol-2-ylidene] palladium(II)

Use Mbook molecular editor to start building the structure. Select the allyl group and the metal and click on “Coordinate”, a new bond is created between the allyl group and the metal. The structure drawn will have the correct molecular formula and weight.

To conclude this tutorial just to mention that all compounds included in the database can be downloaded as .mol, .mol(V3000) and .smi files
