Abstract: We describe the polymorphism of four new bis-hydrazone compounds, namely butane-2,3-dione 2,3-bis{[bis(4-fluorophenyl)methylidene]hydrazone}, C30H22F4N4 (1), butane-2,3-dione 2,3-bis{[bis(4-chlorophenyl)methylidene]hydrazone}, C30H22Cl4N4 (2), butane-2,3-dione 2,3-bis{[bis(4-methylphenyl)methylidene]hydrazone}, C34H34N4 (3), and butane-2,3-dione 2,3-bis({bis[4-(dimethylamino)phenyl]methylidene}hydrazone), C38H46N8 (4), derived by the condensation reaction between substituted benzophenone… read more here.
