Guanidinium complexes arebiologically important as they are present as functional groups in aminoacids. Their physical properties, are so important that they have a variety of applications in the field of ferroelectricity, biotechnology medicine etc. The present work deals about the growth and characterization of guanidinium 3-nitrobenzoate (Gu-3NB), guanidiniumphenylarsonate (GPA), zinc guanidinium phosphate (ZGuP) and guanidiniumchlorochromate (GCC). Structural analysis, linear and non-linear optical properties, Laser damage threshold and thermal stability of the grown crystals have been investigated to check their viability for non-linear optical applications.
