Crystal structure and Hirshfeld surface analysis of (4Z)-1-butyl-4-(2-oxo-propyl-idene)-2,3,4,5-tetra-hydro-1H-1,5-benzodiazepin-2-one.

ABSTRACT: The asymmetric unit of the title compound, C₁₆H₂₀N₂O₂, consists of two independent mol-ecules differing slightly in the conformations of the seven-membered rings and the butyl substituents, where the benzene rings are oriented at a dihedral angle of 34.56 (3)°. In the crystal, pairwise inter-molecular C-H⋯O and complementary intra-molecular C-H⋯O hydrogen bonds form twisted strips extending parallel to (012). These strips are connected into layers parallel to (111) by additional inter-molecular C-H⋯O hydrogen bonds. The layers are further joined by C-H⋯π inter-actions. The Hirshfeld surface analysis of the crystal structure indicates that the most important contributions for the crystal packing are from H⋯H (65.5%), H⋯C/C⋯H (16.0%) and H⋯O/O⋯H (15.8%) inter-actions.

5-Dichloro-acetyl-4-methyl-2,3,4,5-tetra-hydro-1H-1,5-benzodiazepin-2-one hemihydrate.

Project description:There are two crystallographically independent organic mol-ecules in the asymmetric unit of the title compound, C(12)H(12)Cl(2)N(2)O(2)·0.5H(2)O. The benzodiazepine ring adopts a distorted boat conformation in both molecules. The crystal packing is controlled by N-H?O, C-H?O and O-H?O intra- and inter-molecular hydrogen bonds. A graph-set motif of R(3) (3)(14) dimer formation by a combination of N-H?O, O-H?O and C-H?O hydrogen bonds stabilizes the mol-ecules and extends along a axis.

Crystal structure of (Z)-7,8-di-chloro-4-(2-oxo-propyl-idene)-4,5-di-hydro-1H-1,5-benzodiazepin-2(3H)-one.

Project description:In the title compound, C12H10Cl2N2O2, the seven-membered heterocycle displays a half-chair conformation. The mean plane through the oxo-propyl-idene group makes a dihedral angle of 36.44 (9)° with the fused benzene ring. An intra-molecular N-H⋯O hydrogen bond to close an S(6) loop is noted. An important feature of the mol-ecular packing are N-H⋯O hydrogen bonds that lead to the formation of helical supra-molecular chains along the b axis.

Synthesis, crystal structure and Hirshfeld surface analysis of 3-(4,4-dimethyl-2,3,4,5-tetra-hydro-1<i>H</i>-1,5-benzodiazepin-2-yl-idene)-6-methyl-3,4-di-hydro-2<i>H</i>-pyran-2,4-dione.

Project description:The title compound, C17H18N2O3, is constructed from a benzodiazepine ring system linked to a pendant di-hydro-pyran ring, where the benzene and pendant di-hydro-pyran rings are oriented at a dihedral angle of 15.14?(4)°. Intra-molecular N-HDiazp?ODhydp and C-HDiazp?ODhydp (Diazp = diazepine and Dhydp = di-hydro-pyran) hydrogen bonds link the seven-membered diazepine ring to the pendant di-hydro-pyran ring, enclosing S(6) ring motifs. In the crystal, N-HDiazp?ODhydp hydrogen bonds link the mol-ecules into infinite chains along [10]. These chains are further linked via C-HBnz?ODhydp, C-HDhydp?ODhydp and C-HMth?ODhydp (Bnz = benzene and Mth = meth-yl) hydrogen bonds, forming a three-dimensional network. The observed weak C-HDiazp ? ? inter-action may further stabilize the structure. Hirshfeld surface analysis of the crystal structure indicates that the most important contributions for the crystal packing are from H?H (51.1%), H?C/C?H (25.3%) and H?O/O?H (20.3%) inter-actions. Hydrogen bonding and van der Waals inter-actions are the dominant inter-actions in the crystal packing.
