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

ABSTRACT: 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%.

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⋯π and π-π inter-actions [between the five- and six-membered rings of inden-1-one residues; ring centroid-centroid distance = 3.7983 (17) Å].

(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].

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.

(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.

Project description:The mol-ecule of the title compound, C(17)H(15)NO(3), is slightly twisted, with a dihedral angle of 12.12?(3)° between the dihydro-indenone group and the pyridine ring.

(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.

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.
