1-Benzyl-3-[(dimethyl-amino)methyl-ene]-4-phenyl-1H-1,4-benzodiazepin-2(3H)-one.

ABSTRACT: The title compound, C(25)H(23)N(3)O, features a benzene ring fused with a seven-membered 1,4-diazepine ring; the latter ring adopts a boat conformation with the (dimethyl-amino)methyl-bearing C atom as the prow and the fused-ring C atoms as the stern. There are two independent mol-ecules in the asymmetric unit with similar conformations.

4-Phenyl-1H-1,5-benzodiazepin-2(3H)-one.

Project description:In the title compound, C15H12N2O, the phenyl ring makes a dihedral angle of 32.45 (9)° with the benzene ring of the 1,5-benzodiazepin-2-one unit. The seven-membered ring adopts a boat conformation with the methyl-ene group as the prow and the fused benzene-ring C atoms as the stern. In the crystal, inversion dimers linked by pairs of N-H⋯O hydrogen bonds generate R2(2)(8) loops. The dimers are further linked by C-H⋯O hydrogen bonds, so forming a column along the a-axis direction.

Project description:The heterocylic ligand of the polymeric title compound, [CdI(2)(C(22)H(30)N(4))], links two adjacent CdI(2) units, forming a chain running parallel to [[Formula: see text]01]. The Cd(II) atom is located on a twofold rotation axis and shows a distorted tetra-hedral CdI(2)N(2) coordination. The mid-point of the benzene ring of the ligand lies on a center of inversion. There are no classical hydrogen-bonding inter-actions present.

4-Phenyl-1-(prop-2-yn-1-yl)-1H-1,5-benzodiazepin-2(3H)-one.

Project description:4-Phenyl-1H-1,5-benzodiazepin-2(3H)-one reacts in the pres-ence of a concentrated aqueous solution of sodium hydroxide and a quaternary ammonium salt (as catalyst) in benzene (phase transfer catalysis) with propargyl bromide, affording the title benzodiazepine derivative, C(18)H(14)N(2)O. In the mol-ecule, the mean plane of the propargyl substituent is almost perpendicular with that of the amide group [dihedral angle = 87.81?(8)°]. In the crystal, the molecules are linked by C-H?O and C-H?N inter-actions.

6-[(Dimethyl-amino)methyl-ene-amino]-1,3-dimethyl-pyrimidine-2,4(1H,3H)-dione dihydrate.

Project description:Uracil, the pyrimidine nucleobase, which combined with adenine forms one of the major motifs present in the biopolymer RNA, is also involved in the self-assembly of RNA. In the title compound, C(9)H(14)N(4)O(2)·2H(2)O, the asymmetric unit contains one dimethyl-amino-uracil group and two water mol-ecules. The plane of the N=C-NMe(2) side chain is inclined at 27.6?(5)° to the plane of the uracil ring. Both water mol-ecules form O-H?O hydrogen bonds with the carbonyl O atoms of the uracil group. Additional water-water hydrogen-bond inter-actions are also observed in the crystal structure. The O-H?O hydrogen bonds lead to the formation of a two-dimensional hydrogen-bonded network cage consisting of two dimethyl-amino-uracil groups and six water mol-ecules.

5-Acetyl-3-hy-droxy-4-phenyl-4,5-dihydro-1H-1,5-benzodiazepin-2(3H)-one.

Project description:In the title compound, C(17)H(16)N(2)O(3), the seven-membered diazepine ring adopts a boat conformation with the hy-droxy-substituted C atom at the prow and fused benzene ring C atoms at the stern. The phenyl substituent occupies an equatorial position. The amino group of the ring system is a hydrogen-bond donor to the oxo O atom of an inversion-related mol-ecule, and the hy-droxy group is a hydrogen-bond donor to the acetyl O atom of another inversion-related mol-ecule. The two hydrogen bonds generate a ribbon motif parallel to [10[Formula: see text]] in the crystal structure.
