Tris(benzyl-diphenyl-phosphane-κP)(nitrato-κO)silver(I).
Potgieter K, Malan FP, Alimi OA, Meijboom R. Potgieter K, et al. IUCrdata. 2022 Dec 6;7(Pt 12):x221147. doi: 10.1107/S2414314622011476. eCollection 2022 Dec. IUCrdata. 2022. PMID: 36628192 Free PMC article.
The mol-ecular structure of the title complex, [Ag(NO(3))(C(19)H(17)P)(3)], exhibits a severely distorted tetra-hedral coordination environment around the central Ag(I) atom, comprising one O and three P atoms. Apart from a primary Ag-O coordination of the nitrato ligand o …

Weaker neural suppression in autism.
Schallmo MP, Kolodny T, Kale AM, Millin R, Flevaris AV, Edden RAE, Gerdts J, Bernier RA, Murray SO. Schallmo MP, et al. Nat Commun. 2020 May 29;11(1):2675. doi: 10.1038/s41467-020-16495-z. Nat Commun. 2020. PMID: 32472088 Free PMC article.
We show how a computational model that incorporates divisive normalization, as well as narrower top-down gain (that could result, for example, from a narrower window of attention), can explain our observations and divergent previous findings. Thus, weaker neural suppressio …

Copper-Catalyzed Electrochemical C-H Fluorination.
Hintz H, Bower J, Tang J, LaLama M, Sevov C, Zhang S. Hintz H, et al. Chem Catal. 2023 Jan 19;3(1):100491. doi: 10.1016/j.checat.2022.100491. Epub 2023 Jan 9. Chem Catal. 2023. PMID: 36743279 Free PMC article.
The critical challenges of electrocatalysis with a highly reactive Cu(III) species were addressed by the judicious selection of electrolyte, F(-) source, and sacrificial electron acceptor. Catalyst-controlled C-H fluorination occurs with a preference for hydridic C-H …

4-(4-tert-Butyl-benz-yl)-1-neopentyl-1,2,4-triazolium bromide.
Albert DR, Gau M, Rajaseelan E. Albert DR, et al. IUCrdata. 2025 Feb 7;10(Pt 2):x250092. doi: 10.1107/S2414314625000926. eCollection 2025 Feb. IUCrdata. 2025. PMID: 40092360 Free PMC article.
The title 1,2,4-triazolium salt, C(18)H(28)N(3) (+).Br(-), crystallizes in the monoclinic space group Pc. The extended structure exhibits a short inter-molecular inter-action between a heterocyclic C-H group and a bromide ion (HBr = 2.57 A). Additional weaker …

Isoquinolin-5-amine.
Atria AM, Garland MT, Baggio R. Atria AM, et al. Acta Crystallogr C. 2012 Oct;68(Pt 10):o392-4. doi: 10.1107/S0108270112037602. Epub 2012 Sep 7. Acta Crystallogr C. 2012. PMID: 23007540
The supramolecular structure is based on pairs of parallel hydrogen-bonded chains formed by just one molecular type each, defined by the strongest hydrogen bonds in the structure, which are of the N-H...N type. These parallel chains are linked into pairs (or strips) via …

Acetamidoxime.
Olmstead MM, Sahbari JJ. Olmstead MM, et al. Acta Crystallogr C. 2003 Dec;59(Pt 12):o719-20. doi: 10.1107/s0108270103025587. Epub 2003 Nov 30. Acta Crystallogr C. 2003. PMID: 14671381
The oxime of acetamide, viz. N-hydroxyethanimidamide, C(2)H(6)N(2)O, has a complex hydrogen-bonding arrangement in its crystal structure, featuring one strong O-H.N hydrogen bond together with weaker hydrogen bonding involving the amide groups. ...

4-(4-Meth-oxy-phen-yl)-2-methyl-but-3-yn-2-ol.
Eissmann F, Kafurke U, Weber E. Eissmann F, et al. Acta Crystallogr Sect E Struct Rep Online. 2010 Jun 30;66(Pt 7):o1866. doi: 10.1107/S1600536810024529. Acta Crystallogr Sect E Struct Rep Online. 2010. PMID: 21588063 Free PMC article.
The mol-ecular structure of the title compound, C(12)H(14)O(2), features a nearly coplanar arrangement including the aromatic ring, the C C-C group and the ether O atom. ...Further stabilization results from weaker (meth-yl)C-Hpi(acetyl-ene) inter-actions between di …

Quantum chemical studies on hydrogen bonds in helical secondary structures.
Takano Y, Kondo HX, Nakamura H. Takano Y, et al. Biophys Rev. 2023 Jan 6;14(6):1369-1378. doi: 10.1007/s12551-022-01034-5. eCollection 2022 Dec. Biophys Rev. 2023. PMID: 36659988 Free PMC article. Review.
We found that the depolarized electronic structures of the carbonyl oxygen of the ith residue and the amide hydrogen of the (i + 4)th residue cause weaker H-bond in an alpha-helix than in an isolated H-bond. Our calculations showed that the H-bond ener …
