(E)-N'-(2-Hydroxy-benzyl-idene)-2-(4-isobutyl-phen-yl)propanohydrazide.

ABSTRACT: The title hydrazide compound, C(20)H(24)N(2)O(2), exists in a trans configuration with respect to the acyclic C=N bond and an intra-molecular O-H?N hydrogen bond generates an S(6) ring motif. The mean plane through the formohydrazide unit is essentially planar [maximum deviation = 0.025?(2)?Å], and forms dihedral angles of 24.45?(16) and 87.14?(16)° with the two benzene rings. In the crystal structure, inter-molecular N-H?O and C-H?O hydrogen bonds link neighbouring mol-ecules into extended chains along the c axis, which incorporate R(2) (2)(16) ring motifs. An inter-molecular C-H?? inter-action is also observed.

The title hydrazide compound, C(20)H(24)N(2)O(2), exists in a trans configuration with respect to the acyclic C=N bond and an intra-molecular O-H⋯N hydrogen bond generates an S(6) ring motif. The mean plane through the formohydrazide unit is essentially planar [maximum deviation = 0.025 (2) Å], and forms dihedral angles of 24.45 (16) and 87.14 (16)° with the two benzene rings.

N'-[(E)-4-Bromo-benzyl-idene]-2-(4-isobutyl-phen-yl)propanohydrazide.

Project description:The asymmetric unit of the title compound, C(20)H(23)BrN(2)O, contains two independent mol-ecules (A and B), in which the orientations of the 4-isobutyl-phenyl units are different. The dihedral angle between the two benzene rings is 88.45?(8)° in mol-ecule A and 89.87?(8)° in mol-ecule B. Mol-ecules A and B are linked by a C-H?N hydrogen bond. In the crystal, mol-ecules are linked into chains running along the a axis by inter-molcular N-H?O and C-H?O hydrogen bonds. The crystal structure is further stabilized by C-H?? inter-actions. The presence of pseudosymmetry in the structure suggests the higher symmetry space group Pbca. However, attempts to refine the structure in this space group resulted in a disorder model with high R (0.097) and wR (0.257) values. The crystal studied was an inversion twin with a 0.595?(4):0.405?(4) domain ratio.

N'-[(E)-4-Chloro-benzyl-idene]-2-(4-isobutyl-phen-yl)propanohydrazide.

Project description:The asymmetric unit of title compound, C(20)H(23)ClN(2)O, consists of two crystallographically independent mol-ecules (A and B) in which the orientations of the 4-isobutyl-phenyl units are different. The isobutyl group of mol-ecule B is disordered over two positions with occupancies of 0.850?(5) and 0.150?(5). The dihedral angle between the two benzene rings is 88.70?(9)° in mol-ecule A and 89.38?(9)° in mol-ecule B. The independent mol-ecules are linked together into chains along [100] by N-H?O and C-H?O hydrogen bonds, and by C-H?? inter-actions. In the chain, N-H?O and C-H?O hydrogen bonds generate R(2) (1)(6) ring motifs. In addition, C-H?N hydrogen bonds are observed. The presence of pseudosymmetry in the structure suggests the higher symmetry space group Pbca but attempts to refine the structure in this space group resulted in high R (0.119) and wR (0.296) values.

(E)-4-(4-Hydr-oxy-3-methoxy-benzyl-idene-amino)-3-[1-(4-isobutyl-phen-yl)eth-yl]-1H-1,2,4-triazole-5(4H)-thione.

Project description:The asymmetric unit of the title compound, C(22)H(26)N(4)O(2)S, contains two crystallographically independent mol-ecules (A and B). The isobutyl unit of mol-ecule B is disordered over two orientations with refined occupancies of 0.785?(6) and 0.215?(6). In each mol-ecule, intra-molecular C-H?S hydrogen bonds generate S(6) ring motifs. The essentially planar 1,2,4-triazole rings [r.m.s. deviations of 0.004?(2) and 0.011?(2)?Å, in A and B respectively] form dihedral angles of 85.86?(12), 8.38?(10)°, respectively, with the isobutyl-substituted phenyl ring and the 2-methoxy-phenol substituent in mol-ecule A [89.26?(13) and 2.46?(10)°, respectively, in B]. In the crystal structure, inter-molecular N-H?N and N-H?S hydrogen bonds link neighbouring mol-ecules, generating R(2) (2)(7) ring motifs. These molecules are further inter-connected into extended chains along [20] by inter-molecular O-H?O hydrogen bonds. The crystal structure is further stabilized by ?-?
