Synthesis,crystal growth and characterization of organic nonlinear optical Piperaziniummalonatesesquihydrate

Piperazniummalonatesesquihydrate (PMA) was successfully synthesized from aqueous solution. PMA crystallized in triclinic system with PI space group. The functional groups present in the title compound were confirmed by FTIR spectral studies. UV-Vis spectral studies endowed that the PMA crystal has active in the entire visible region. LDT studies divulged the optical resistance of PMA crystal using Nd: YAG laser. Mechanical stability was established from the Vicker's hardness studies. The grown PMA crystal was examined for third order susceptibility by Z-scan technique and revealed the saturable absorption and self defocusing behavior of PMA crystal.
