(2E)-2-(4-Meth-oxy-benzyl-idene)-2,3-di-hydro-1H-inden-1-one.

ABSTRACT: In the title compound, C(17)H(14)O(2), the indan-1-one system is almost planar (r.m.s. deviation = 0.007?Å) and the benzene ring is twisted out of its plane by 8.15?(6)°. The conformation about the C=C double bond [1.348?(2)?Å] is E. Helical supra-molecular chains along [010] feature in the crystal packing; these are sustained by C-H?O hydrogen bonds and ?-? inter-actions between translationally related indan-1-one systems [centroid-centroid distance = 3.7970?(10)?Å].

In the title compound, C(17)H(14)O(2), the indan-1-one system is almost planar (r.m.s. deviation = 0.007 Å) and the benzene ring is twisted out of its plane by 8.15 (6)°. The conformation about the C=C double bond [1.348 (2) Å] is E. Helical supra-molecular chains along [010] feature in the crystal packing; these are sustained by C-H⋯O hydrogen bonds and π-π inter-actions between translationally related indan-1-one systems [centroid-centroid distance = 3.7970 (10) Å]. ...[more]

Project description:The title indan-1-one derivative, C(16)H(11)BrO, is planar, the r.m.s. deviation for all 18 non-H atoms being 0.071?Å. The configuration about the C=C bond [1.337?(5)?Å] is E.

The studied crystal was an inversion twin.

Ortho-rhom-bic polymorph of (2E)-2-(2,3-dihydro-1H-inden-1-yl-idene)-2,3-di-hydro-1H-inden-1-one.

Project description:The title compound, C(18)H(14)O, is polymorphic at 123 K. The ortho-rhom-bic form reported herein has two independent mol-ecules in the asymmetric unit, with mol-ecular volume 313.5 Å(3). The previously reported triclinic (P-1) form [Raston & Scott (2000 ▶). Green Chem., 2, 49-52] has mol-ecular volume 309.6 Å(3) at the same temperature. All three mol-ecules deviate significantly and systematically from the putative C(s) symmetry (δ(r.m.s.) = 0.0265, 0.0256, 0.0497 Å). Comparison of the two molecules in the orthorhombic polymorph shows that 16 of the 19 equivalent pairs of framework atoms have a mirror-image pattern of deviations (above/below plane), suggesting that the two are quasi-enanti-omorphs. The pattern of deviations in the triclinic form is nearly the same (13 of 19 atom pairs) as the ortho-rhom-bic form.

2-(Di-phenyl-methyl-idene)-2,3-di-hydro-1H-inden-1-one.

Project description:In the title mol-ecule, C22H16O, the indanone ring system is approximately planar with a dihedral angle between the fused rings of 5.13?(14)°. Two benzene rings are linked together at one side of a double bond, sitting on either side of the indanone ring system and making dihedral angles of 70.30?(12) and 44.74?(13)° with it. In the crystal, hydrogen bonding is not present, but weak C-H?? or ?-? inter-actions occur and mol-ecules form a sheet-like structure in the bc plane.

(E)-2-[4-(Trifluoro-meth-yl)benzyl-idene]-2,3-dihydro-1H-inden-1-one.

Project description:In the title mol-ecule, C(17)H(11)F(3)O, the indan ring system and the trifluoro-methyl-substituted benzene ring are approximately individually planar and form a dihedral angle of 1.81?(5)° with each other. In the crystal, mol-ecules are linked by pairs of weak bifurcated (C-H)(2)?O hydrogen bonds to form centrosymmetric dimers, generating R(2) (1)(6) and R(2) (2)(10) ring motifs. These dimers are connected by further weak C-H?O hydrogen bonds into one-dimensional chains along the b axis. Weak C-H?? inter-actions are also present.

(E)-2-(3,4-Dimeth-oxy-benzyl-idene)-5,6-dimeth-oxy-2,3-dihydro-1H-inden-1-one.

Project description:In the title compound, C(20)H(20)O(5), the 2,3-dihydro-1H-indene ring system is essentially planar [maximum deviation = 0.010 (1) Å] and is inclined at an angle of 4.09 (4)° with respect to the phenyl ring. The C=C bond has an E configuration. In the crystal, the mol-ecules are linked into chains propagating in [102] via inter-molecular C-H⋯O hydrogen bonds. The crystal structure is further consolidated by C-H⋯π inter-actions.

(E)-2-(3-Chloro-benzyl-idene)-5,6-dimeth-oxy-2,3-dihydro-1H-inden-1-one.

Project description:In the title compound, C(18)H(15)ClO(3), the dihydro-indenone group makes a dihedral angle of 8.56 (6)° with the bezene ring. In the crystal, the mol-ecules are inter-connected into a three-dimensional network via inter-molecular C-H⋯O hydrogen bonds. Weak C-H⋯π and π⋯π [centroid-centroid distances 3.6598 (9)-3.6913 (9) Å] inter-actions are also observed.

(1E,2E)-1,2-Bis(2,3-dihydro-1H-inden-1-yl-idene)hydrazine.

Project description:In the title compound, C(18)H(16)N(2), there are two independent half-mol-ecules (A and B) in the asymmetric unit, each mol-ecule being completed by an inversion center situated in the mid-point of the central N-N bond. The mol-ecules themselves therefore are essentially planar with r.m.s. deviations of 0.015 (1) and 0.020 (1) Å, respectively. In the crystal, mol-ecules are connected via C-H⋯π inter-actions in which only type B mol-ecules are donors, while both A and B mol-ecules act as acceptors. As a result, type B mol-ecules are linked into infinite chains along b, which are inter-connected by molecules of type A.

(2E)-2-(Furan-2-yl-methyl-idene)-2,3-dihydro-1H-inden-1-one.

Project description:In the title compound, C(14)H(10)O(2), the five-membered ring of the inden-1-one residue is almost planar (r.m.s. deviation = 0.035?Å). A twist about the single bond linking the two residues is evident [C-C-C-C torsion angle = -13.2?(5)°]. The three-dimensional architecture is stabilized by C-H?O (involving the trifurcated carbonyl O atom), C-H?? and ?-? inter-actions [between the five- and six-membered rings of inden-1-one residues; ring centroid-centroid distance = 3.7983?(17)?Å]. The sample studied was a non-merohedral twin; the minor component refined to approximately 36%.

Crystal structure of (Z)-3-(4-meth-oxy-benzyl-idene)-2,3-di-hydro-benzo[b][1,4]thia-zepin-4(5H)-one.

Project description:In the title compound, C17H15NO2S, the two C atoms linking the S and carbonyl C atoms of the seven-membered thia-zepine ring are disordered over two sites, with occupancies of 0.511 (4) and 0.489 (4); both disorder components adopt distorted twist-boat conformations. In the crystal, N-H⋯O and C-H⋯O hydrogen bonds link inverted-related mol-ecules into dimers, incorporating R 1 (2)(6) and R 2 (2)(8) ring motifs; the acceptor carbonyl O atom is bifurcated. These dimers are further linked by C-H⋯O hydrogen bonds, forming supra-molecular tapes running along the a axis.

(2E)-2-[(2H-1,3-Benzodioxol-5-yl)methyl-idene]-2,3-dihydro-1H-inden-1-one.

Project description:In the title compound, C(17)H(12)O(3), each of the five-membered rings in the inden-1-one and 1,3-benzodioxole residues is almost planar (r.m.s. deviations = 0.041 and 0.033 Å, respectively). A small twist about the single bond linking the two residues is evident [the C-C-C-C torsion angle = 8.7 (4)°]. Supra-molecular zigzag layers propagating in the ac plane are formed in the crystal via C-H⋯O inter-actions. The layers are linked via π-π inter-actions between the five- and six-membered rings of 1,3-benzodioxole residues [centroid-centroid distance = 3.4977 (14) Å].
