N2 - A new organic nonlinear optical crystal, 4-dimethylaminobenzaldehyde-4-nitrophenylhydrazone (DANPH), has been prepared and investigated with regard to polymorphism, growth, and characterization of the structural and physical properties. Recrystallization of DANPH in various solvents under different conditions showed the existence of three crystalline phases, a co-crystal (form I) of DANPH with benzene in a ratio 4 to 1 in space group P21212, red greenish prisms (form II) in space group Cc, and red orange plates (form III) in space group PS1/c. The growth of crystals with interesting linear and nonlinear optical properties (form II) was investigated by using different growth techniques: solution growth, gel growth and physical vapor transport growth. With these methods bulk crystals, very thin plates, and films were grown, respectively. By the analysis of crystal structures and phase stabilities of the forms II and III, the mechanism of polymorphism was investigated.
