Abstract
The [Cu-2(dap)(5)](ClO4)(4) complex (dap=1,3-diaminopropane) crystallizes, in almost quantitative yield, from alcoholic solutions containing the ligand and Cu(II) in a 5:2 molar ratio. Crystals of [Cu-2(dap)(5)](ClO4)(4) are orthorhombic, space group Pbca, a=14.737(7), b=15.710(4),c=39.995(9) Angstrom,Z=8. As revealed by the crystal structure a dap molecule bridges two Cu(dap)(2)(2+) units. Each copper atom is five-coordinated in a rather regular square-pyramidal environment, the two nitrogen atoms of the bridging dap occupying the apical positions. The basal planes of the square pyramids form a dihedral angle of 61.7(2)degrees
