Direct Synthesis of Novel Polymeric Bimetallic Phthalimide Complex: poly{catena-(bis(μ- phthalimido-N,O,O')-bis(μ-phthalimido-N,O)- -aqua-dipropanol-copper(II)disodium}

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)4Na2(PrOH)2H2O]n was synthesized and characterized by a single crystal X-ray crystallography and IR spectroscopy. The copper(II) ions have a distorted tetrahedral environment (CuN4), while the coordination polyhedra of two symmetrically independent sodium ions are distorted tetragonal pyramid (NaO5) and octahedron (NaO6). 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.
