The structure of the β-phase of (1-phenyl-3-(2-[(2-aminoethyl)amino]-ethylimino)-1-buten-1-olato-O,N,N',N") palladium(II) perchlorate, β-[Pd(baden)]ClO4, was solved by the heavy atom method and refined anisotropically to R = 0.035 for 11 226 unique observed reflections. The title compound is orthorhombic, a = 14.152(2), b = 12.507(1), c = 20.012(2) Å, Pca21, Z = 8. The structure contains two symmetrically independent molecules both formed by two five-membered and two six-membered rings (one of them is phenyl) and disordered perchlorate anion. The crystal packing is predominantly given by electrostatic interactions accompanied by weak hydrogen bonding among nitrogens and perhlorate oxygens. No structural significant differences between α- and β-phases were found.
