(5E)-2-[4,5-Bis(methylsulfanyl)-1,3-dithiol-2-ylidene]-5-(4-iodo-1,3-dithiol-2-ylidene)-1,3-dithiolan-4-one
The mol-ecular framework of the title compound, C(11)H(7)IOS(8), is almost planar [maximum deviation = 0.040 (4) Å], except for the two methyl-sulfanyl groups, which are twisted relative to the mol-ecular skeleton, making C-S-C-C torsion angles of 144.1 (8) and -141.3 (8)°. In the crystal, mol-ecules are stacked alternately in opposite orientations, forming a one-dimensional column parallel to ...
متن کامل4-(Pyridin-2-yl)-1,3-dithiol-2-one
In the title compound, C(8)H(5)NOS(2), the non-H atoms are approximately coplanar [maxium deviation = 0.060 (3) Å]. The dihedral angle between the least-squares planes of the pyridine and 1,3-dithiol-2-one rings is 5.96 (17)°. The crystal packing is stabilized by weak inter-molecular C-H⋯O hydrogen bonds and by an S⋯S close contact [3.510 (5) Å].
متن کاملBis-DCM Type Dyes: Convenient Method for Synthesis of 2-(2, 6-bis(4-(dialkylamino)styryl)-4H -pyran-4-ylidene) Malononitrile Derivatives
An efficient and convenient method for synthesis of 2,6-bis (4-(dialkylamino) styryl)-4H-pyran-4-one starting from 4- (dialkylamino) benzaldehyde with 2,6-dimethyl-4H-pyran-4-onein the presence of MeONa as the base was described. Additionally, preparation of novel compounds with bis-DCM-type skeleton for application in organic light-emitting diodes was developed via reactio...
متن کامل2-{3-Cyano-4-[2-(4-diethylamino-2-hydroxyphenyl)ethenyl]-5,5-dimethyl-2,5-dihydrofuran-2-ylidene}malononitrile acetone 0.25-solvate
In the title compound, C(22)H(22)N(4)O(2)·0.25C(3)H(6)O, the disordered acetone mol-ecule lies with partial occupancy about the 2 axis. The mol-ecule of the malononitrile derivative is essentially planar excluding the methyl groups, with the largest deviation from the mean plane through the non-H atoms being 0.1955 (13) Å. Two rotamers with different orientations of the benzene ring are observe...
متن کامل2,5-Bis(1,3-dithiol-2-ylidene)-1,3-dithiolane-4-thione
The asymmetric unit of the title compound, C(9)H(4)S(7), contains two independent mol-ecules, in one of which the central five-membered ring is disordered over two orientations in a 0.924 (3):0.076 (3) ratio. The mol-ecular skeleton is almost planar: the average distance of the atoms from their mean plane is 0.128 (7) Å in the ordered mol-ecule, and 0.088 (5) and 0.123 (2) Å in the major and mi...
