Direct synthesis of novel polymeric bimetallic phthalimide complex: poly{catena-(bis(μ3-phthalimido-N,O,O')-bis(μ2-phthalimido-N,O)-aqua-dipropanol-copper(II)disodium}

摘要

As a result of the direct synthesis through oxidative dissolution of metalliccopper powder in the presence of phthalimide and sodium hydride a newpolymeric bimetallic coordination compound [Cu(phthal)4Na2(PrOH)2H2O]n wassynthesized and characterized by a single crystal X-ray crystallography and IRspectroscopy. The copper(II) ions have a distorted tetrahedral environment (CuN4),while the coordination polyhedra of two symmetrically independent sodium ionsare distorted tetragonal pyramid (NaO5) and octahedron (NaO6). The alternatingCu and Na coordination spheres are bridged by the O atoms of the multidentatephthalimide anions. In the crystal lattice, columns of the polymeric complex arepacked in the pseudo-hexagonal mode. The complex crystallizes in the triclinicspace group P-1 with the unit cell parameters: a = 11.293(4) ?, b = 12.253(5) ?,c = 15.683(5) ?, α = 92.60(4)°, β = 106.39(5)°, γ = 113.39(5)°.
