Science
The H2 site of the aniline NH2 group in molecule A is bonded to the sulfonyl O site A2 of a B molecule of the opposite handedness (H2∙∙∙and), and the A and B molecules involved in this particular interaction are related by a local glide-reflection operation [38].
Science
The crystal structure of polymorph II has the space group symmetry P21/n and contains two independent molecules, A and B. The H3 site in the NH2 group of molecule A is bonded to the imido nitrogen site A1 and additionally to the sulfonyl-O site A2 of a second A molecule (H3∙∙∙A1 and H3∙∙∙A2).
Science

Expert writing Tips
Best practice
When describing chemical structures or reactions, use "molecule is bonded" to clearly indicate that a chemical bond exists between the molecule and another atom or molecule. Be specific about the type of bond if known (e.g. covalent bond, hydrogen bond).
Common error
Avoid using incorrect verb tenses or forms such as "molecule was bond" or "molecule is bonding". The correct form is "molecule is bonded" to indicate a completed bonding process.
