Synthesis and crystal structure of a polymeric zinc(II) complex derived from 4-nitro- phenylacetic acid and propane-1,3-diamine

Abstract

A new polymeric zinc(II) complex, [ZnL₂(PDA)]_n, has been prepared by the reaction of zinc sulfate, 4-nitrophenylacetic acid, and propane-1,3-diamine (PDA) in water. Structure of the complex has been characterized by single-crystal X-ray diffraction. The complex crystallizes as orthorhombic space group Pnma, with unit cell dimensions a = 15.732(1) Å, b = 23.912(1) Å, c = 5.5565(3) Å, V = 2090.2(2) ų, Z = 4, R₁ = 0.0427, wR₂ = 0.0968, S = 1.048. The Zn atom is coordinated in a tetrahedral geometry. Single crystals of the complex are stabilized by hydrogen bonds and p···p interactions.
