4,4′-Bipyridinium bis(perchlorate)–4-aminobenzoic acid–4,4′-bipyridine–water (1/4/2/2)
In the structure of the title compound, C(10)H(10)N(2) (2+)·2ClO(4) (-)·4C(7)H(7)NO(2)·2C(10)H(8)N(2)·2H(2)O, the 4,4'-bipyridinium cation has a crystallographically imposed centre of symmetry. The cation is linked by N-H⋯N hydrogen bonds to adjacent 4,4'-bipyridine mol-ecules, which in turn inter-act via O-H⋯N hydrogen bonds with 4-amino-benzoic acid mol-ecules, forming chains running parallel...
متن کامل4-Aza-1-azoniabicyclo[2.2.2]octane–2-aminobenzoate–2-aminobenzoic acid (1/1/1)
A 4-aza-1-azoniabicyclo-[2.2.2]octane cation, a 2-amino-benzoate anion and a neutral 2-amino-benzoic acid mol-ecule comprise the asymmetric unit of the title compound, C(6)H(13)N(2) (+)·C(7)H(6)NO(2) (-)·C(7)H(7)NO(2). An intra-molecular N-H⋯O hydrogen bond occurs in the anion and in the neutral 2-amino-benzoic acid mol-ecule. The cation provides a charge-assisted N-H⋯O hydrogen bond to the ani...
متن کاملMechanism of inactivation of myeloperoxidase by 4-aminobenzoic acid hydrazide.
Hypochlorous acid is the most powerful oxidant generated by neutrophils and is likely to contribute to the damage mediated by these inflammatory cells. The haem enzyme myeloperoxidase catalyses its production from hydrogen peroxide and chloride. 4-Aminobenzoic acid hydrazide (ABAH) is a potent inhibitor of hypochlorous acid production. In this investigation we show that, in the presence of hydr...
متن کامل(4-Aza-1-azoniabicyclo[2.2.2]octane-κN 4)trichloridocobalt(II)
In the title compound, [CoCl(3)(C(6)H(13)N(2))], the tetra-hedrally coordinated Co(II) ion has Co-Cl distances ranging from 2.2220 (11) to 2.2449 (9) Å and a Co-N distance of 2.056 (2) Å. In the crystal, N-H⋯Cl hydrogen bonds link mol-ecules into chains in [010]. Weak C-H⋯Cl inter-actions stabilize further the crystal packing.
متن کامل1-{2-[4-(4-Nitrophenyl)piperazin-1-yl]ethyl}-4-aza-1-azoniabicyclo[2.2.2]octane iodide
The title compound, C(18)H(28)N(5)O(2) (+)·I(-), was observed as a main product in an intended 1:1 reaction between 4-iodo-nitro-benzene and 1,4-diaza-bicyclo-[2.2.2]octane (DABCO). In the reaction, DABCO undergoes a ring opening to yield a quaternary salt of DABCO and 1-ethyl-4-(4-nitro-phen-yl)piperazine with an iodide anion. The crystal structure determination was carried out as no crystal s...
