Single crystals of a new modification of the di(nitrato)di(aqua)palladium(II) complex β-trans-[Pd(NO3)2(H2O)2] were obtained. Their crystal structure was determined: monoclinic crystal system, a = 5.7469(4) Å, b = 5.3942(6) Å, c = 10.0956(10) Å, β = 97.401(3)°, P21/c, Z = 2, d calc = 2.851 g/cm3, Bruker X8 APEX CCD, MoK α , 836 independent reflections, room temperature. The square-plane coordination of the Pd atom is formed by four oxygen atoms (Pd-O(NO3) 2.003(3) Å and Pd-O(H2O) 2.021(4) Å) and completed to a distorted bipyramid by two intramolecular contacts (Pd…O(NO3) 2.893 Å). A comparative crystal-chemical analysis with α-trans-[Pd(NO3)2(H2O)2] was carried out.
