(orcid)0000-0001-9071-4506 Trans-amidate platinum complexes anchoring water and N-donor molecules. The importance of hydrogen bonding 2022 Access copy available to the general public Unrestricted The square planar bisnitrile platinum(II) derivatives PtCl2(NCR)2 (R=Ph (1 a); Et (1 b); p-C6H4F (1 c); p-C6H4tBu (1 d); m-C6H3Me2 (1 e); o, p-C6H2Me3 (1 f)) react with tetrabutylammonium hydroxide to render the monoaquo NBu4]trans-PtCl(HNCOR)2(OH2)] (2 a–2 f). The water molecule is s-coordinated to platinum and the binding is reinforced by two strong hydrogen bonds to the neighboring amidate ligands (OH···OC). Substitution of water in 2 a by N-donor ligands can be efficiently achieved only in the presence of a dehydrating agent as magnesium sulphate or 4 Å molecular sieves. By following this strategy, compounds NBu4]trans-PtCl(HNCOPh)2(NH2R’)] (R’=H (3), NH2 (4), tBu (5 a), p-C6H4Me (5 b) have been isolated. The incoming ligands are s-coordinated to platinum and also establish strong hydrogen bonds to the amidates (NH···OC). Treatment of 2 a with halogens causes oxidation at the metal center, rendering the platinum(IV) derivatives NBu4]PtClX2(HNCOPh)2(OH2)] (X=Cl (6 a), Br (6 b), I (6 c)). info:eu-repo/grantAgreement/ES/DGA/E17-20R info:eu-repo/grantAgreement/ES/MICINN/PID2021-122869NB-I00 info:eu-repo/grantAgreement/ES/MICIU-FEDER/PGC2018-094749-B-I00 info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 2.3 2022 CHEMISTRY, INORGANIC & NUCLEAR 21 / 42 = 0.5 2022 Q2 T2 0.527 2022 Inorganic Chemistry 2022 Q2 4.4 2022 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Martín, A.
