Its crystal structure is formed of neutral zig-zag chains in which the nona-coordinated Dy(iii) atoms (O(9)donor set) are linked by PDOA ligands with a chelating-bridging coordination mode. DC and AC magnetic studies revealed that1behaves as a field-induced SMM with three relaxation channels. The derived values, considering the Orbach relaxation process, of the barrier to spin reversal and the extrapolated relaxation time areU/k(B)= 59.5 K and tau(0)= 6.3 x 10(-10)s, respectively.Ab initiocalculations support the experimental results.2020http://zaguan.unizar.es/record/10660810.1039/d0nj02276dhttp://zaguan.unizar.es/record/106608oai:zaguan.unizar.es:106608info:eu-repo/grantAgreement/ES/DGA/E11-20Rinfo:eu-repo/grantAgreement/ES/DGA/M4info:eu-repo/grantAgreement/ES/MINECO-FEDER/PGC2018-093451-B-I00NEW JOURNAL OF CHEMISTRY 44, 31 (2020), 13458-13465All rights reservedhttp://www.europeana.eu/rights/rr-f/info:eu-repo/semantics/openAccess
