NGC 2355 was observed with the Large Binocular Camera at the Large Binocular Telescope using the Bessel B, V, and Ic filters. The cluster parameters have been obtained using the synthetic colour-magnitude diagram method, as done in other papers of this series. Additional spectroscopic observations with the Fibre-fed Echelle Spectrograph at the Nordic Optical Telescope of three giant stars were used to determine the chemical properties of the cluster. Our analysis shows that NGC 2355 has metallicity slightly less than solar, with [Fe/H]=-0.06dex, age between 0.8 and 1Gyr, reddening E(B-V) in the range 0.14-0.19mag, and distance modulus (m-M)0 of about 11mag. We also investigate the abundances of O, Na, Al, {alpha}, iron-peak, and neutron capture elements, showing that NGC 2355 falls within the abundance distribution of similar clusters (same age and metallicity). The Galactocentric distance of NGC 2355 places it at the border between two regimes of metallicity distribution; this makes it an important cluster for the study of the chemical properties and evolution of the disc.2015MNRAS.453.4185Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/453/4185CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/PASJ/56/295 : BVIc photometry of old open clusters (Hasegawa+, 2004)J/A+A/429/607 : BV photometry of Berkeley 36, 73 and 34 (Ortolani+, 2005)J/A+A/464/573 : VI photometry of 5 open clusters (Carraro+, 2007)J/MNRAS/424/1132 : BVI photometry of Be 27, Be 24 and Be 36 (Donati+, 2012)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/453/4185https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/453/4185http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/453/4185https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/453/4185https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/453/4185http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/453/4185GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/453/4185/photom (BVI photometric catalogue)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/453/4185/photom?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/453/4185/photom?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/453/4185/photom?GETtext/xml+votable180.050000true109.147636413.57564740.0055555555555555566/22498-22499 22505https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/453/4185?format=asciiOpticalInfrareddefaultJ/MNRAS/453/4185/photomBVI photometric catalogueIDID numbermeta.idintrecnoRecord number assigned by the VizieR team.
