Project description:In the title compound, [Fe(C5H5)(C20H13N2O2)], the substituted cyclo-penta-dienyl ring and quinoline system are approximately coplanar, making a dihedral angle of 5.18 (6)°, while the dihedral angle between the quinoline system and the benzene ring is 28.45 (8)°. There is high thermal motion in the free cyclo-penta-dienyl ring compared with the substituted cyclo-penta-dienyl ring. The conformation of the two cyclopentadienyl rings in the ferrocenyl moiety is eclipsed.

Project description:In the title compound, [Fe(C(5)H(5))(C(16)H(14)N(3)O(3))], the pyrazoline ring and the substituted cyclo-penta-dienyl ring are nearly coplanar, with a dihedral angle of 8.17 (2)°, while the nitro-substituted benzene ring is twisted out of the pyrazoline ring plane by 70.76 (1)°. The mol-ecules in the crystal structure are held together by three inter-molecular C-H⋯O hydrogen bonds. There is also an intra-molecular C-H⋯N hydrogen bond. The H atoms of the methyl group are disordered equally over two positions.

Project description:The title ferrocene derivative, [Fe(C5H5)2(C8NO2)], including an alkyne bonded to a para-nitro-phenyl substituent, which was synthesized from a copper-free Sonogashira cross-coupling reaction between ethynylferrocene and 4-bromo-1-nitro-benzene, crystallizes in the P21/n space group. In the ferrocene unit, the penta-dienyl (Cps) rings are in an eclipsed conformation. The angle of rotation between the substituted cyclo-penta-dienyl ring and the p-nitro-phenyl group is 6.19 (10)°, yielding a quasi-linear extension of the ferrocenyl substitution. Important inter-molecular inter-actions arise from π-π stacking between the Cp rings and the p-nitro-phenyl, from corners of the Cp rings that are perpendicularly aligned, and between the O atoms from the nitro substituent and carbons at the corners of the Cp rings, propagating along all three crystallographic axes.

Project description:In the title compound, [Fe(C(5)H(5))(C(14)H(10)NO(3))], one cyclo-penta-diene ring is substituted and one is unsubstituted. The two rings are almost parallel and are eclipsed and ordered. The conjugated substituent is slightly twisted with respect to the cyclo-penta-diene ring. The crystal structure contains four inter-molecular C-H?O hydrogen-bonds in the range 3.324?(3)-3.539?(3)?Å and one ?(aryl ring)-? (Cp ring) stacking inter-action with a ring-centroid distance of 3.894?(2)?Å.

Project description:In the title compound, C(11)H(9)NO(2), the mean planes formed by the phenyl and acryl group are almost orthogonal to each other, with a dihedral angle of 88.61?(7)°. The carbonitrile side chain is almost linear, the C-C-N angle being 179.54?(16)°. In the crystal, mol-ecules are linked by inter-molecular O-H?O inter-actions into infinite chains running parallel to the b axis.

Project description:In the mol-ecule of the title compound, C(14)H(10)N(2)O(4), the dihedral angle formed by the benzene rings is 53.66 (5)°. In the crystal structure, mol-ecules are linked into chains parallel to the [01] direction by inter-molecular C-H⋯O hydrogen-bonding inter-actions.

Project description:In the structure of the title compound, [Fe(C(5)H(5))(C(14)H(10)N)], the unsubstituted cyclo-penta-diene (Cp) ring is disordered over two positions, with site-occupancy factors 0.76 (2) and 0.24 (2). The dihedral angles between the substituted Cp ring and the major and the minor components of the disordered ring are 0.9 (5) and 6(2)°, repectively. The plane of the acrylonitrile unit makes dihedral angles of 6.1 (18) and 6.5 (4)° with the substituted Cp ring and the phenyl ring planes, respectively.

Project description:The title compound, C(13)H(9)N(3)O(5), prepared as a solid derivative of 3-nitro-analine via reaction with 4-nitro-benzoyl chloride, crystallizes in a chiral space group. The mol-ecule is non-planar with a dihedral angle of 26.1?(1)° between the two benzene rings. Both nitro groups are twisted slightly out of the plane of their corresponding benzene rings, making dihedral angles of 10.7?(4) and 13.5?(4)°. The mol-ecules are stacked along the a axis with benzene ring centroid-centroid distances of 3.8878?(6)?Å. In the crystal, inter-molecular benzene C-H?O inter-actions involving one nitro group and the carbonyl group link the mol-ecules, forming chains along [001]. An additional set of aromatic C-H?O inter-actions with the second nitro group form chains along [101], connecting adjacent chains to create layers perpendicular to the b axis.

Project description:In the title compound, C(20)H(18)N(2)O(3), the C=C bond of the acrylonitrile group that links the indole and the 3,4,5-trimeth-oxy-phenyl rings has Z geometry, with dihedral angles between the plane of the acrylonitrile unit and the planes of the benzene and indole ring systems of 21.96?(5) and 38.94?(7)°, respectively. The acrylonitrile group is planar (r.m.s. deviation from planarity = 0.037?Å). Mol-ecules are linked into head-to-tail chains that propagate along the b-axis direction by bifurcated N-H?O inter-molecular hydrogen bonds, which form an R(1) (2)(5) motif between the indole NH group and the two meth-oxy O atoms furthest from the nitrile group.
