N-Acetyl-N-[2,4-dicyano-1-(4-meth-oxy-phen-yl)-9,10-dihydro-phenanthren-3-yl]acetamide.

ABSTRACT: In the title compound, C(27)H(21)N(3)O(3), the cyclo-hexa-1,3-diene ring has a screw-boat conformation, and the fused ring system is folded, the dihedral angle between the outer benzene rings being 27.61?(6)°. The N-acetyl-acetamide residue (r.m.s. deviation = 0.0935?Å) has an anti conformation and is essentially perpendicular to the benzene ring to which it is connected [dihedral angle = 89.14?(6)°]; the meth-oxy-benzene group is also twisted out of this ring [dihedral angle = 59.47?(7)°]. The three-dimensional architecture is consolidated by C-H?O and C-H?? inter-actions.

A second monoclinic polymorph for 3-amino-1-(4-meth-oxy-phen-yl)-9,10-dihydro-phenanthrene-2,4-dicarbonitrile.

Project description:The title compound, C(23)H(17)N(3)O, has been previously described in a monoclinic P2(1)/c polymorph with Z = 4 [Asiri, Al-Youbi, Faidallah, Ng & Tiekink (2011). Acta Cryst. E67, o2449]. In the new monoclinic P2(1)/n form, with Z = 8, there are two independent mol-ecules, A and B, in the asymmetric unit. In both mol-ecules, the cyclo-hexa-1,3-diene ring has a screw-boat conformation, whereas it is a distorted half-chair in the original polymorph. There is a fold in each mol-ecule, as indicated by the dihedral angle between the benzene rings of the 1,2-dihydro-naphthalene and aniline residues of 33.19?(10)° (mol-ecule A) and 30.6?(10)° (mol-ecule B). The meth-oxy-benzene ring is twisted out of the plane of the aniline residue to which it is connected [dihedral angles = 49.22?(10) and 73.27?(10)°, in A and B respectively]. In the crystal, the two independent mol-ecules self-associate via N-H?N hydrogen bonds, generating a 12-membered {?HNC(3)N}(2) synthon. These are connected into a supra-molecular tape in the (-101) plane by N-H?O(meth-oxy) inter-actions. In the P2(1)/c polymorph, supra-molecular layers are formed by N-H?N and N-H?O inter-actions.

3-Amino-1-(4-meth-oxy-phen-yl)-9,10-dihydro-phenanthrene-2,4-dicarbonitrile.

Project description:In the title compound, C(23)H(17)N(3)O, significant deviations from planarity are evidenced. This is quanti-fied in the dihedral angles formed between the central amino-benzene ring and the benzene rings of the meth-oxy-benzene [67.93?(8)°] and 1,2-dihydro-naphthalene [28.27?(8)°] residues. In the crystal the amino-H atoms form hydrogen bonds to the meth-oxy-O atom and to one of the cyano-N atoms to generate a two-dimensional array with a zigzag topology that stacks along the ([Formula: see text][Formula: see text] 1) plane.

3-Amino-1-(3,4-dimeth-oxy-phen-yl)-9,10-dihydro-phenanthrene-2,4-dicarbonitrile.

Project description:In the title compound, C(24)H(19)N(3)O(2), the partially saturated ring adopts a distorted half-chair conformation with the methyl-ene-C atom closest to the amino-benzene ring lying 0.664?(3)?Å out of the plane defined by the five remaining atoms (r.m.s. deviation = 0.1429?Å. The dihedral angle [32.01?(10)°] between the benzene rings on either side of this ring indicates a significant fold in this part of the mol-ecule. The dimeth-oxy-substituted benzene ring is almost orthogonal to the benzene ring to which it is attached [dihedral angle = 72.03?(9)°]. The mol-ecule has been observed previously as the major component of a 1:19 co-crystal with 2-amino-4-(3,4-dimeth-oxy-phen-yl)-5,6-dihydro-benzo[ha]quinoline-3-carbonitrile [Asiri et al. (2011). Acta Cryst. E67, o2873-o2873]. Supra-molecular chains with base vector [201] are formed in the crystal structure via N-H?O hydrogen bonds between the amino H atoms of one mol-ecule inter-acting with the meth-oxy O atoms of a neighbouring mol-ecule. The chains are linked into a three-dimensional architecture by C-H?? inter-actions.

1-{[(2,3-Dihydro-1H-inden-2-yl)-oxy]meth-yl}quinazoline-2,4(1H,3H)-dione.

Project description:In the title mol-ecule, C(18)H(16)N(2)O(3), the five-membered ring has an envelope conformation, with the substituted C atom deviating by 0.342 (4) Å from the mean plane P calculated for the remainder of the non-H atoms of the 2,3-dihydro-1H-indene fragment. The mean planes of quinazoline-2,4(1H,3H)-dione fragment and P form a dihedral angle of 59.08 (4)°. In the crystal, pairs of N-H⋯O hydrogen bonds link mol-ecules into inversion dimers, and weak C-H⋯O hydrogen bonds and π-π inter-actions between the benzene rings of the quinazoline ring systems [centroid-centroid distance = 3.538 (3) Å] further consolidate the packing.

Project description:In the title compound, C(26)H(25)NO(6), the anthraquinone ring system forms a dihedral angle of 15.5?(1)° with the benzene ring of the dimethyl-aniline group.

Project description:The mol-ecule of the title compound, C(22)H(23)N(3)O(4), features a benzodiazepine fused-ring system whose seven-membered ring adopts a boat-shaped conformation (with the C atoms of the fused-ring as the stern and the methine C atom as the prow). The methyl-ene C atom connected to the methine C atom occupies an equatorial position. The methyl-ene C atom is connected to the five-membered oxazole ring, both of which are disordered over two positions in a 0.634 (4):0.366 (4) ratio. Weak inter-molecular C-H⋯O hydrogen bonding is present in the crystal structure.
