Zusammenfassung:	<jats:title>Abstract</jats:title><jats:p>We present the performances of a 330 g zinc molybdate (ZnMoO<jats:sub>4</jats:sub>) crystal working as scintillating bolometer as a possible candidate for a next generation experiment to search for neutrinoless double beta decay of <jats:sup>100</jats:sup>Mo. The energy resolution, evaluated at the 2615 keV <jats:italic>γ</jats:italic>-line of <jats:sup>208</jats:sup>Tl, is 6.3 keV FWHM. The internal radioactive contaminations of the ZnMoO<jats:sub>4</jats:sub> were evaluated as <6 μBq/kg (<jats:sup>228</jats:sup>Th) and 27±6 μBq/kg (<jats:sup>226</jats:sup>Ra). We also present the results of the <jats:italic>α</jats:italic> vs <jats:italic>β</jats:italic>/<jats:italic>γ</jats:italic> discrimination, obtained through the scintillation light as well as through the study of the shape of the thermal signal alone.</jats:p>
