Di-tert-butyl 2,2'-[9H-fluorene-9,9-diylbis(p-phenyl-ene-oxy)]diacetate.

ABSTRACT: In the title mol-ecule, C(37)H(38)O(6), the non-fused C atom belonging to the five-membered ring of the fluorene system is connected to two p-phenyl-ene rings, the rings opening up the C(ar-yl)-C-C(ar-yl) angle to 113.1?(1)°. The four-atom -O-CH(2)-C(=O)-O- chain between the p-phenyl-ene ring and the tert-butyl group assumes a more regular W-shaped conformation for one substituent [O-C-C-C torsion angle = 171.9?(2)°] but a less regular W-shaped conformation for the other [torsion angle = 147.4?(2)°].

4,4'-Di-tert-butyl-2,2'-[imidazolidine-1,3-diylbis(methyl-ene)]diphenol.

Project description:In the title compound, C25H36N2O2, the two tert-butyl-substituted benzene rings are inclined at an angle of 53.5 (3)° to one another. The imidazolidine ring has an envelope conformation with with one of the C atoms of the ethylene fragment as the flap. The structure displays two intra-molecular O-H⋯N hydrogen bonds that generate S(6) ring motifs. The crystal studied was a non-merohedral twin with a fractional contribution of 0.281(6) for the minor domain.

Di-tert-butyl 2,2'-(biphenyl-2,2'-diyl-dioxy)diacetate.

Project description:The title compound, C(24)H(30)O(6), does not exhibit π-π inter-actions due to the steric effect of the bulky tert-butyl groups present in the mol-ecule. The presence of these groups at the 2 and 2' positions hinders the free motion of the benzene rings relative to each other, causing them to adopt an anti-periplanar arrangement. The benzene rings are twisted by just under 50.96 (17)° with respect to each other. The carbonyl groups within the mol-ecule are directed in different directions, one towards the biphenyl group and the other away from it. The mol-ecules are linked together by C=O⋯H-C hydrogen bonds.

Di-tert-Butyl 2,2'-[2,2'-methyl-enebis(naphthalene-2,1-diyldi-oxy)]diacetate.

Project description:In the title compound, C(33)H(36)O(6), two naphthalene ring systems are connected through a methyl-ene linkage [C-C-C = 114.9 (2)°]; the ring systems are aligned at an angle of 76.5 (1)°. Of the two -O-CH(2)-C(=O)-C(CH(3))(3) substituents, one adopts an extended conformation whereas the other is U-shaped. In the crystal, mol-ecules are linked via weak C-H⋯O hydrogen bonding, forming supra-molecular chains running along the c axis.

2,2'-Bi(9,9-di-ethyl-fluorene).

Project description:The title compound, C34H34, systematic name 9,9,9',9'-tetra-ethyl-2,2'-bi(9H-fluorene), crystallized with two crystallographically independent mol-ecules (A and B) in the asymmetric unit. These differ mainly in the orientation of the lateral ethyl chains: in mol-ecule A, they are both on the same side of the mol-ecule whereas in mol-ecule B, one di-ethyl-fluorene moiety has undergone a 180° rotation such that the two pairs of ethyl residues appear on opposite sides of the mol-ecule. The fluorene ring systems subtend dihedral angles of 31.37 (4) and 43.18 (3)° in mol-ecules A and B, respectively. Hence the two fluorene moieties are tilted slightly toward one another. This may be due to the presence of inter-molecular C-H⋯π inter-actions between neighboring mol-ecules. The lateral ethyl chains (excluding H atoms) are also almost planar, with each pair almost perpendicular to the plane of the fluorene system to which they are attached with dihedral angles between the ethyl and fluorene planes in the range 86.04 (8)-89.5 (1)°.

6,6'-Di-tert-butyl-4,4'-dimeth-oxy-2,2'-[1,3-diazinane-1,3-diylbis(methyl-ene)]diphenol 0.19-hydrate.

Project description:In the title hexa-hydro-pyrimidine derivative, C(28)H(42)N(2)O(4)·0.19H(2)O, the 1,3-diazinane ring has a chair conformation with a diequatorial substitution. The asymmetric unit contains one half-organic mol-ecule and a solvent water mol-ecule with occupany 0.095. The mol-ecule lies on a mirror plane perpendicular to [010] which passes through the C atoms at the 2- and 5-positions of the heterocyclic system. The partially occupied water mol-ecule is also located on this mirror plane. The dihedral angle between the planes of the aromatic rings is 17.71?(3)°. Two intra-molecular O-H?N hydrogen bonds with graph-set motif S(6) are present. No remarkable inter-molecular contacts exist in the crystal structure.
