The crystal structure of 1 is formed by zig-zag chains in which the Cu(II) atoms are linked by bridging PDOA2- ligands in a bis(monodentate) fashion via carboxylate oxygen donor atoms. The Cu(II) central atom is penta-coordinated by five oxygen atoms from two different PDOA2- ligands and three oxygen atoms of the aqua ligands yielding an O2O3 donor set. Hydrogen bonds of the O-H···O type afford a 2D supramolecular structure with short distances of 4.8562(7) and 5.1431(7) Å between the Cu(II) atoms. DC magnetic studies in the temperature range 2 – 300 K revealed antiferromagnetic exchange interactions via hydrogen bonds which were corroborated by theoretical calculations. 000162967 536__ $$9info:eu-repo/grantAgreement/ES/DGA/E11-23R$$9info:eu-repo/grantAgreement/ES/MICINN/PID2021-124880NB-I00 000162967 540__ $$9info:eu-repo/semantics/embargoedAccess$$aby-nc-nd$$uhttps://creativecommons.org/licenses/by-nc-nd/4.0/deed.es 000162967 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/acceptedVersion 000162967 700__ $$aStolárová, Monika Pataky 000162967 700__ $$aTomás, Milagros 000162967 700__ $$aTitiš, Ján 000162967 700__ $$0(orcid)0000-0002-0444-996X$$aFalvello, Larry R.$$uUniversidad de Zaragoza 000162967 700__ $$aCernák, Juraj 000162967 7102_ $$12010$$2760$$aUniversidad de Zaragoza$$bDpto.
