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}

Abstract

As a result of the direct synthesis through oxidative dissolution of metallic copper powder in the presence of phthalimide and sodium hydride a new polymeric bimetallic coordination compound [Cu(phthal) 4 Na 2 (PrOH) 2 H 2 O]n was synthesized and characterized by a single crystal X-ray crystallography and IR spectroscopy. The copper(II) ions have a distorted tetrahedral environment (CuN 4 ), while the coordination polyhedra of two symmetrically independent sodium ions are distorted tetragonal pyramid (NaO 5 ) and octahedron (NaO 6 ). The alternating Cu and Na coordination spheres are bridged by the O atoms of the multidentate phthalimide anions. In the crystal lattice, columns of the polymeric complex are packed in the pseudo-hexagonal mode. The complex crystallizes in the triclinic space group P-1 with the unit cell parameters: a = 11.293(4) Å, b = 12.253(5) Å, c = 15.683(5) Å, α = 92.60(4)˚, β = 106.39(5)˚, γ = 113.39(5)˚. 74 A.
