3,3',5,5'-Tetra-bromo-2,2'-bithio-phene.

ABSTRACT: The title compound, C(8)H(2)Br(4)S(2), was prepared by bromination of 2,2'-bithio-phene with bromine. The mol-ecule is located on a crystallographic twofold rotation axis, thereby imposing equal geometry of the two thio-phene rings. Each five-membered ring is planar [maximum deviation 0.011?(9)?Å] and the dihedral angle between the planes through the rings is 47.2?(4)°. The mol-ecules are arranged to minimize intramolecular contacts between the 3-3' and 5-5'-bromine atoms.

Project description:The complete mol-ecule of the title compound, C(10)H(4)N(2)S(2), is generated by an inversion center situated at the mid-point of the bridging C-C bond. The bithio-phene ring system is planar [maximum deviation = 0.003 (2) Å] and the central C-C bond length is 1.450 (2) Å. There are no significant inter-molecular inter-actions in the crystal structure, which is stabilized by van der Waals inter-actions.

Diammonium 1,1',3,3'-tetra-methyl-2,2',4,4',6,6'-hexa-oxoperhydro-5,5'-bipyrimidine-5,5'-diide monohydrate.

Project description:In the title hydrated salt, 2NH(4) (+)·C(12)H(12)N(4)O(6) (2-)·H(2)O, the two hexa-hydro-pyrimidine rings in the dianion are inclined to one another at a dihedral angle of 62.76?(5)°. In the crystal structure, the anions and water mol-ecules are linked into sheets parallel to the bc plane by inter-molecular O-H?O hydrogen bonds and sustained by C-H?O contacts. The linking of the anions and water mol-ecules with the cations by N-H?O hydrogen bonds creates a three-dimensional extended network. The crystal structure is further stabilized by very weak C-H?? inter-actions.

3,3',5,5'-Tetra-nitro-biphen-yl.

Project description:The title compound, C(12)H(6)N(4)O(8), is a biphenyl system that was synthesized as a building block for a new series of anti-malarial compounds. The aromatic rings are oriented at a dihedral angle of 45.5?(2)°, and inter-molecular short O?O contacts form a chain along the b axis. The strength of the inter-actions involved in this chain cause one of the rings to be slightly distorted, with the torsion angle between the nitro groups being 23.4?(2)°, whereas, in the other ring, both nitro systems are parallel, forming an angle of 9.6?(2)° with the plane of the aromatic ring to which they are bound. Furthermore, the three ring C atoms around the ring-ring linkage belong to a plane inclined by 4.5?(1)° in relation to the plane containing the other three C atoms, i.e. (NO(2)-)C-C-C(NO(2)). This distortion of the ring causes uncommonly short intermolecular O?O [3.038?(2)?Å] and O?C [3.000?(4) and 3.214?(1)?Å] contacts.

{3,3',5,5'-Tetra-meth-oxy-2,2'-[ethane-1,2-diylbis(nitrilo-methyl-idyne)]diphenol-ato}-copper(II).

Project description:In the title square-planar copper complex, [Cu(C(20)H(22)N(2)O(6))], the Cu-N and Cu-O bond lengths are significantly longer than those of its isostructural nickel analog. The title structure is related to that of the corresponding monohydrate. There are significant differences in the conformations of the two complexes. While the monohydrate is mainly planar, in the title compound there is a slight twist in the two benzene rings at each end of the complex [dihedral angle = 13.14?(6)°]. All the atoms of the meth-oxy substitutents are in the plane of the ring to which they are attached (r.m.s. deviation = 0.0079?Å) except for one of the meth-oxy C atoms, which deviates slightly [0.309?(4)?Å]. In the crystal, weak C-H?O inter-molecular inter-actions link the mol-ecules.
