In the title compound, [CaCu(2)(C(9)H(13)N(4)O(4))(2)(CH(3)OH)(2)](n), the Ca(II) atom lies on an inversion center and is situated in a moderately distorted octa-hedral environment. The Cu(II) atom is in a distorted square-pyramidal geometry, defined by four N atoms belonging to the amide and oxime groups of the triply deprotonated residue of N,N'-bis-(2-hydroxy-imino-propano-yl)propane-1,3-diamine (H(4)pap) and one oxime O atom from a neighboring Hpap ligand at the apical site, forming a dimeric [Cu(2)(Hpap)(2)](2-) unit. Each dimeric unit connects four Ca atoms and each Ca atom links four [Cu(2)(Hpap)(2)](2-) units through Ca-O(amide) bonds, leading to a three-dimensional framework. The crystal structure involves intra- and inter-molecular O-H⋯O hydrogen bonds.
