4-Nitroanilinium triiodide monohydrate
In the title compound, C(6)H(7)N(2)O(2) (+)·I(3) (-)·H(2)O, the triiodide anions form two-dimensional sheets along the a and c axes. These sheets are separated by the 4-nitro-anilinium cations and water mol-ecules, which form part of an extended hydrogen-bonded chain with the triiodide along the c axis, represented by the graph set C(3) (3)(14). The second important hydrogen-bonding inter-actio...
متن کاملtrans-Dioxidotetrapyridinerhenium(V) triiodide
In the title salt, [ReO(2)(C(5)H(5)N)(4)]I(3), the cation and anion are both located on centres of symmetry. The Re(V) atom adopts a trans-ReO(2)N(4) octa-hedral coordination and short intra-molecular C-H⋯O contacts occur within the cation. In the crystal, the cations form layers perpendicular to [100] and a weak C-H⋯O inter-action links the cations.
متن کامل8-Iodoquinolinium triiodide tetrahydrofuran solvate
The title compound, C(9)H(7)IN(+)·I(3) (-)·C(4)H(8)O, was synthesized from 8-amino-quinoline using the Sandmeyer reaction. The 8-iodo-quinolinium cation is essentially planar and the triiodide ion is almost linear. N-H⋯O hydrogen bonds, and inter-molecular I⋯I [3.7100 (5) Å] and I⋯H inter-actions, between the cation, anion and solvent mol-ecules result in the formation of sheets oriented parall...
متن کاملTriiodide derivatization in protein crystallography.
Methods for producing protein derivatives using cryosoak techniques with triiodide solutions are described. The methods have been tested using six different proteins. SAD/SIRAS phasing was attempted for each protein using data measured with conventional Cu Kalpha X-ray equipment and synchrotron radiation. Refinement of all six derivative structures showed that iodine is able to bind as I(-) (as...
متن کاملNonaaquapraseodymium triiodide–thiourea (1/2)
The title compound, [Pr(H(2)O)(9)]I(3)·2CS(NH(2))(2), an adduct of nona-aqua-praseodymium triiodide with two thio-urea mol-ecules, is composed from [Pr(H(2)O)(9)](3+) cations (polyhedron: monocapped tetra-gonal anti-prism), noncoordinated thio-urea mol-ecules and iodide anions. The components are evidently connected by hydrogen bonds but in the presence of heavy atoms water H atoms have not bee...
