Аннотация:Crystal structures of five derivatives of dienediaminoketones - 3-amino-3-(dimethylamino)-2-[(3-oxo-1,3-dihydro-2H-indol-2-ylidene)methyl]acrylonitrile (1); 3-amino-2-[(3-oxo-1,3-dihydro-2Hindol-2-ylidene)methyl]-3-pyperidin-1-ylacrylonitrile (2); 3-amino-3-morpholin-4-yl-2-[(3-oxo-1,3dihydro-2H-indol-2-ylidene)methyl]acrylonitrile (3); 3-amino-3-[(4-methoxyphenyl)amino]-2-[(3-oxo-1,3-dihydro-2H-indol-2-ylidene)methyl]acrylonitrile (4) and 3-amino-3-(benzylamino)-2-[(3-oxo-1,3-dihydro-2H-indol-2-ylidene)methyl]acrylonitrile (5) - were determined from powder patterns measured with the laboratory powder diffractometer. The single crystal structure of the hydrate of ethanol solvate of 3 3-0 center dot 33C(2)H(6)O center dot 0.33H(2)O (3a) - is also presented. The hydrogen-bonding patterns of all compounds are discussed.
