Editing Polyatomic ion (section)

== Zwitterion and polycharged polyatomic ions ==
Many polyatomic molecules can carry spatially separated charges, forming zwitterions or, in general, polycharged polyatomic ions. A typical example are [[Amino acid|amino acids]], which carry both charged amino and carboxyl groups. These charges can influence the chemical<ref>{{Cite journal |last=Pizzi |first=Andrea |last2=Dhaka |first2=Arun |last3=Beccaria |first3=Roberta |last4=Resnati |first4=Giuseppe |date=2024-07-01 |title=Anion⋯anion self-assembly under the control of σ- and π-hole bonds |url=https://pubs.rsc.org/en/content/articlelanding/2024/cs/d3cs00479a |journal=Chemical Society Reviews |language=en |volume=53 |issue=13 |pages=6654–6674 |doi=10.1039/D3CS00479A |issn=1460-4744|doi-access=free }}</ref>  and physical properties of substances.<ref>{{Cite journal |last=Novikov |first=Anton P. |last2=Safonov |first2=Alexey V. |last3=German |first3=Konstantin E. |last4=Grigoriev |first4=Mikhail S. |date=2023-12-18 |title=What kind of interactions we may get moving from zwitter to “dritter” ions: C–O⋯Re(O4) and Re–O⋯Re(O4) anion⋯anion interactions make structural difference between L-histidinium perrhenate and pertechnetate |url=https://pubs.rsc.org/en/content/articlelanding/2024/ce/d3ce01164j |journal=CrystEngComm |language=en |volume=26 |issue=1 |pages=61–69 |doi=10.1039/D3CE01164J |issn=1466-8033}}</ref>
