The planar dihydroxo-bridged [Cu 2 (dpyam) 2 (μ-OH) 2 I 2 ].2H 2 O (1) and the roof-shaped trihydroxo-bridged [Cu 2 (dpyam) 2 (μ-OH) 3 ]Cl.3H 2 O (2) (in which dpyam = di-2-pyridylamine) dinuclear copper(II) compounds have been synthesized and their crystal structures determined by X-ray crystallographic methods. All of compounds are being centrosymmetric molecule. Compound 1 contains a dinuclear [I(dpyam)Cu(μ-OH) 2 Cu(dpyam)I] + unit with a strictly planar CuO 2 network, dihedral angle between the CuO 2 planes of 180 o . Each copper(II) ion is in a tetrahedrally distorted square pyramidal coordination geometry of the CuN 2 O 2 I chromophore with a dihedral angle 19.3 o between the CuN 2 and CuO 2 planes. In the dinuclear [(dpyam)Cu(μ-OH) 3 Cu(dpyam)] + unit of compound 2, the triply bridged Cu(II) ions show a distorted square pyramidal coordination. The fifth apical ligand is a longer bonded bridging OH - group, at distance of 2.433(4) A, which joins the basal CuN 2 O 2 planes in a roof-shaped configuration with a dihedral angle of 142.5 o . The Cu-Cu distance is 2.803(7) A.
