8-Meth-oxy-3-(4-methyl-benzyl-idene)-6-(prop-1-en-yl)chroman-4-one.

ABSTRACT: In the title compound, C(21)H(20)O(3), the tolyl ring makes a dihedral angle of 31.11 (6)° with the benzene ring of the chromanone unit. The pyrone ring adopts a half-chair conformation. The mol-ecular structure is stabilized by a weak intra-molecular C-H⋯O inter-action and the crystal packing is stabilized by weak inter-molecular C-H⋯O inter-actions and a C-H⋯π inter-action.

(E)-N-(4-{[1-(Prop-2-en-1-yl)-1H-1,2,3-triazol-4-yl]meth-oxy}benzyl-idene)morpholin-4-amine.

Project description:The asymmetric unit of the title compound, C17H21N5O2, contains two crystallographically independent mol-ecules, which are linked by a C-H⋯N hydrogen bond. The morpholine rings of both mol-ecules adopt distorted chair conformations. The dihedral angles between the triazole and benzene rings are 12.8 (3)° in the first independent molecule in which the -N=C- group between the morpholine and benzene rings is disordered [site-occupancy ratio = 0.576 (7):0.424 (7)] and 88.1 (2)° in the second independent mol-ecule. In the crystal, mol-ecules are linked by C-H⋯N hydrogen bonds along the [100] direction. In addition, one weak C-H⋯π inter-action and two weak π-π stacking inter-actions [centroid-centroid distances = 3.840 (3) and 3.823 (2) Å] between the triazole rings of adjacent mol-ecules are observed. The atoms of the terminal propenyl groups in both mol-ecules are disordered over two sets of sites [site-occupancy ratios = 0.691 (10):0.309 (10) and 0.705 (15):0.295 (15)].

N'-[Bis(benzyl-sulfan-yl)methyl-idene]-4-meth-oxy-benzohydrazide.

Project description:In the title compound, C(23)H(22)N(2)O(2)S(2), the dihedral angles between the 4-meth-oxy-substituted phenyl ring and the other two phenyl rings are 84.4?(4) and 77.7?(1)°, respectively, while the dihedral angle between the two phenyl rings is 57.5?(2)°. The amino group is not involved in an N-H hydrogen bond. The crystal packing is established by inter-molecular C-H?O packing inter-actions involving a relatively rare weak three-center hydrogen bond between the keto O atom and H atoms of the two nearby phenyl rings, which link the mol-ecules into chains running along the a axis. Additional weak inter-molecular hydrogen-bond inter-actions between the 4-meth-oxy O atom and one of the phenyl rings and provide added stability to the crystal packing.

(2E)-3-(6-Meth-oxy-naphthalen-2-yl)-1-[4-(methyl-sulfan-yl)phen-yl]prop-2-en-1-one.

Project description:The asymmetric unit of the title compound, C(21)H(18)O(2)S, consists of two crystallographically independent mol-ecules (A and B). The mol-ecules exist in a trans conformation with respect to the central C=C bond. The naphthalene ring system makes dihedral angles of 51.62 (12) (mol-ecule A) and 52.69 (12)° (mol-ecule B) with the benzene ring. In mol-ecule A, the prop-2-en-1-one group forms dihedral angles of 22.84 (15) and 29.02 (12)° with the adjacent naphthalene ring system and benzene ring, respectively, whereas the corresponding angles are 30.04 (12) and 23.33 (12)° in mol-ecule B. In the crystal, mol-ecules are linked by inter-molecular C-H⋯O hydrogen bonds into head-to-tail chains along the a axis. The crystal packing also features C-H⋯π inter-actions. The crystal studied was a pseudo-merohedral twin with twin law (100 0-10 00-1) and a refined component ratio of 0.6103 (16):0.3897 (16).
