These differences in bond types can give rise to problems with software and formats that only supports the other bond types. Both these situations are handled by Rdkit without problems.įor the coordinate or dative bond, which this blog post is about, one atom donates both electrons into a covalent bond forming with another atom possessing an empty orbital. However, if the electronegativity differences are large enough, a ionic bond is formed where the most electronegative atom attracts both electrons. This gives a molecular orbital with two electrons. A regular covalent bond is formed when two atoms combine orbitals with only one electron each. Chemical Bond Types and File FormatsĬhemical bonds come in a variety of versions.

Read on if you want to learn more about how to handle these kind of compounds with Rdkit. A common problem arises with organometallic compound and coordinate bonds. Sometimes the used software did not support a correct way, so the users found a workaround, which can give rise to errors with other software packages. Most often the problem arises as creative users in the past have had a problem with registering a compound the way they wanted it. When I have been working with chemical databases and import of molecules I have encountered numerous problems with the way chemical structures are drawn.
