Dimethyl (2-hydroxy-4-phenylbut-3-en-2-yl)phosphonate
In the title compound, C(12)H(17)O(4)P, the phenyl-butenyl group is disordered over two sets of sites with an occupancy ratio of 0.755 (12):0.245 (12). In the crystal, inversion dimers linked by pairs of O-H⋯O hydrogen bonds occur, forming R(2) (2)(10) ring motifs. The packing is consolidated by weak C-H⋯π inter-actions.

The asymmetric unit of the title compound, C(21)H(26)O(4)S, consists of two independent mol-ecules. In both mol-ecules, intra-molecular O-H⋯O hydrogen bonds stabilize the mol-ecular structure. In the crystal, each mol-ecule and its symmetry-related mol-ecule by twofold rotation form a dimer through a pair of inter-molecular C-H⋯O hydrogen bonds. In one of the mol-ecules, the thio-phene group is...

The mol-ecular conformation of the title compound, C(18)H(18)O(5), is stabilized by a strong intra-molecular hydrogen bond between the hydroxyl and carbonyl groups. The C=C double bond displays an E configuration while the carbonyl group shows an S-cis configuration relative to the double bond. The dihedral angle between the two rings is 15.0 (1)°.

The title compound, C(16)H(28)N(2)O(3)S, is dimerized by inversion symmetry-related inter-molecular O-H⋯N hydrogen bonding, forming an R(2) (2)(16) motif. The dimers are also linked through inter-molecular C-H⋯O hydrogen bonding. The compound is chiral with a stereogenic centre located in the thia-zole ring, but in the crystal structure it forms a racemate. The thia-zole ring has an envelope co...
متن کامل(2E)-3-[4-(Dimethylamino)phenyl]-1-(2,5-dimethyl-3-thienyl)prop-2-en-1-one
The asymmetric unit of the title compound, C(17)H(19)NOS, contains two independent mol-ecules which differ in the dihedral angles between the five- and six-membered rings [12.52 (10) and 4.63 (11)°]. Weak inter-molecular C-H⋯O hydrogen bonds link the two independent mol-ecules into pseudocentrosymmetric dimers. In one mol-ecule, the O atom of the carbonyl group is disordered over two positions ...
