2',7'-Di-bromo-spiro-[cyclo-propane-1,9'-fluorene].

ABSTRACT: In the title compound, C15H10Br2, each mol-ecule is situated on special postion mm, so the asymmetric unit contains one-quater of a mol-ecule. The 2,7-di-bromo-9H-fluorene fragment and three spiro-cyclo-propane C atoms lie on different planes, which are perpendicular to each other. In the crystal, ?-? inter-actions between aromatic rings [inter-centroid distance = 3.699?(3)?Å] pack the mol-ecules into stacks extending in [001].

In the title compound, C15H10Br2, each mol-ecule is situated on special postion mm, so the asymmetric unit contains one-quater of a mol-ecule. The 2,7-di-bromo-9H-fluorene fragment and three spiro-cyclo-propane C atoms lie on different planes, which are perpendicular to each other. In the crystal, π-π inter-actions between aromatic rings [inter-centroid distance = 3.699 (3) Å] pack the mol-ecules into stacks extending in [001]. ...[more]

Crystal structure of (R)-6'-bromo-3,3-dimethyl-3',4'-di-hydro-2'H-spiro-[cyclo-hexane-1,3'-1,2,4-benzo-thia-diazine] 1',1'-dioxide.

Project description:In the title compound, C14H19BrN2O2S, the 1,2,4-thia-diazinane ring adopts an envelope conformation with the N atom (attached to the sulfonyl group) as the flap, while the cyclo-hexane ring adopts a chair conformation. The mean plane of the cyclo-hexane ring is almost normal to the benzene ring and the mean plane of the 1,2,4-thia-diazinane ring, making dihedral angles of 70.4 (2) and 71.43 (19)°, respectively. Furthermore, the dihedral angle between the benzene ring and the mean plane of the 1,2,4-thia-diazinane ring is 4.91 (18)°. The mol-ecular structure is stabilized by an intra-molecular C-H⋯O hydrogen bond, which encloses an S(6) ring motif. In the crystal, mol-ecules are linked by N-H⋯O hydrogen bonds into chains along [10-1], forming a C(6) graph-set motif. These chains are inter-connected via C-H⋯π inter-actions, leading to chains along [-101], so finally forming sheets parallel to (010).

Crystal structure of diethyl 3-(3-chloro-phen-yl)-2,2-di-cyano-cyclo-propane-1,1-di-carboxyl-ate.

Project description:In the racemic title compound, C17H15ClN2O4, which has been synthesized and the crystal structure of the solvent-free mol-ecule determined, the angle between the planes of the benzene and cyclo-propane rings is 54.29 (10)°. The mol-ecular conformation is stabilized by two weak intra-molecular C-H⋯Ocarbox-yl inter-actions. In the crystal, C-H⋯O hydrogen bonds form centrosymmetric cyclic R 2 (2)(10) dimers which are linked into chain substructures extending along c. Further C-H⋯Nnitrile hydrogen bonding, including a centrosymmetric cyclic R 2 (2)(14) association, link the chain substructures, forming a two-dimensional layered structure extending across the approximate ab plane. No significant π-π or halogen-halogen inter-molecular inter-actions are present in the crystal.

Project description:The title compound, [Cu(4)Br(4)(C(21)H(22)Br(2)N(4))(4)], features a macrocyclic Cu(4)L(4) ring system in which each Cu(I) atom is coordinated by one bromide ion and two N atoms from two 2,2'-dimethyl-1,1'-[2,2-bis-(bromo-meth-yl)propane-1,3-di-yl]di(1H-benzimidazole) (L) ligands in a distorted trigonal-planar geometry. The L ligands adopt either a cis or trans configuration. The asymmetric unit contains one half-mol-ecule with the center of the macrocycle located on a crystallographic center of inversion. Each bromide ion binds to a Cu(I) atom in a terminal mode and is oriented outside the ring. The macrocycles are inter-connected into a two-dimensional network by ?-? inter-actions between benzimid-azole groups from different rings [centroid-centroid distance = 3.803?(5)?Å.

[N,N'-Bis(4-bromo-benzyl-idene)-2,2-di-methyl-propane-?N,N']iodidocopper(I).

Project description:The title compound, [CuI(C(19)H(20)Br(2)N(2))], lies across a crystallographic mirror plane. The coordination around the copper centre is distorted trigonal planar, with a bite angle of 94.7?(3)°. A six-membered chelate ring in a chair conformation is formed by the coordination of the imine N atoms of the bidentate ligand to the Cu(I) atom. This conformation is required by the crystallographic mirror symmetry. The inter-planar angle between the benzene rings is 74.85?(19)°. The crystal structure exhibits weak inter-molecular C-H?? inter-actions, which link the mol-ecules into chains along the b axis.
