Experimental techniques (X-ray diffraction, DSC and spectral methods) and computational approaches (molecular and crystal structure modeling, and crystal habit modeling) have been applied to a large series of organic compounds forming polymorphs and polytypes. Examples of concomitant polymorphism and induced conformational polymorphism are presented. Influence of crystallization conditions and hydrogen bonds on crystal structure and crystal habit for crystals build of polar organic molecules is discussed.
