Synthesis, crystal structures, and third-order nonlinear optical properties of two novel complexes of H4edbbp with Zn(II), Cd(II)

We synthesized a new organo-diphosphonic acid ligand H2O 3PCH(Ph)NH(CH2)2NH(Ph)CHPO3H 2 [ethane-1,2-diamino-N,N′-bis(benzyl phosphonic)acid, H 4edbbp] and its two complexes [NH3CH(CH 3)CH2NH3]2M2(edbbp) 2·H2O [M=Zn(II) (1), Cd(II) (2)] in this paper. The complexes 1-2 were structurally characterized by means of X-ray single crystal diffraction. The central ion (M=Zn or Cd) has a distorted square-pyramidal coordination environment by three oxygen atoms from phosphonate units and two nitrogen atoms of H4edbbp. The fundamental structural units [M 2(edbbp)2]4- are linked by extensive intermolecular hydrogen bonds between 1,2-propyldiamine cations and phosphonate oxygen atoms, forming a one-dimensional chain structure. The third-order nonlinear optical (NLO) properties of 2 were determined by Z-scan techniques. NLO refractive index n2, χ(3) of 2's, and hyperpolarizability γ values were calculated to be 1.31×10 -17 m2 W-1, 3.19×10-11 and 8.57×10-30 esu, respectively. The results indicate that complex 2 exhibits very strong NLO absorption and self-focusing effects.
