Poly[bis-(mu(4)-oxalato)potassium(I)praseodymium(III)].
Kummoon K, Laksee S, Chainok K. Kummoon K, et al. IUCrdata. 2025 Jul 11;10(Pt 7):x250607. doi: 10.1107/S2414314625006078. eCollection 2025 Jul. IUCrdata. 2025. PMID: 40777618 Free PMC article.
The asymmetric unit of the title oxalate-bridged bimetallic coordination polymer, [KPr(C(2)O(4))(2)] (n) , contains one Pr(3+) cation, one K(+) cation, one complete C(2)O(4) (2-) anion, and one half of each of two C(2)O(4) (2-) anions positioned on crystallographic …

Atomic-Scale Study of Cation Ordering in Potassium Tungsten Bronze Nanosheets.
Li L, Jiang F, Tu F, Jia S, Gao Y, Wang J. Li L, et al. Adv Sci (Weinh). 2017 Apr 26;4(9):1600537. doi: 10.1002/advs.201600537. eCollection 2017 Sep. Adv Sci (Weinh). 2017. PMID: 28932660 Free PMC article.
It has long been accepted that the formation of superlattices in hexagonal-based potassium tungsten bronzes is attributed to K vacancies only, together with small displacements of W cations. Here, the superlattices within potassium tungsten bronze nanosheets both st …

Weak Cation Selectivity in HCN Channels Results From K(+)-Mediated Release of Na(+) From Selectivity Filter Binding Sites.
Bauer D, Wissmann J, Moroni A, Thiel G, Hamacher K. Bauer D, et al. Function (Oxf). 2022 Apr 22;3(3):zqac019. doi: 10.1093/function/zqac019. eCollection 2022. Function (Oxf). 2022. PMID: 36156894 Free PMC article.
Furthermore, simulations provide a thermodynamic explanation for the weak cation selectivity of HCN channels that contain only two ion binding sites in the selectivity filter (SF). We find that sodium ions bind more strongly to the SF than potassium and are easier r …

Coupling of a viral K+-channel with a glutamate-binding-domain highlights the modular design of ionotropic glutamate-receptors.
Schönrock M, Thiel G, Laube B. Schönrock M, et al. Commun Biol. 2019 Feb 22;2:75. doi: 10.1038/s42003-019-0320-y. eCollection 2019. Commun Biol. 2019. PMID: 30820470 Free PMC article.
Based on partial sequence and structural similarities, these complex cation-permeable iGluRs are thought to descend from simple bacterial proteins emerging from a fusion of a substrate binding protein (SBP) and an inverted potassium (K(+))-channel. ...

A modular approach to carbene-stabilized diphosphorus species.
Doddi A, Bockfeld D, Zaretzke MK, Kleeberg C, Bannenberg T, Tamm M. Doddi A, et al. Dalton Trans. 2017 Nov 21;46(45):15859-15864. doi: 10.1039/c7dt03436a. Dalton Trans. 2017. PMID: 29114655
Heteroleptic N-heterocyclic dicarbene-diphosphorus species were prepared by reaction of the carbene-phosphinidene adduct (IPr)PSiMe(3) (1, IPr = 1,3-bis(2,6-diisopropylphenyl)imidazolin-2-ylidene) with the carbene-phosphorus trichloride adduct (IMes)PCl(3) (2, IMes = 1,3-bis(2,4, …

Ion binding to cucurbit[6]uril: structure and dynamics.
Tarmyshov KB, Müller-Plathe F. Tarmyshov KB, et al. J Phys Chem B. 2006 Jul 27;110(29):14463-8. doi: 10.1021/jp0622637. J Phys Chem B. 2006. PMID: 16854157
Complexes with Na(+) and K(+) mostly involve one cation, whereas with Ca(2+) single- and double-cation complexes are formed in similar proportions. The binding dynamics strongly depends on the type of cation. A smaller size or higher charge increases the resi …
