4,11-Diaza-1,8-diazoniacyclotetradecane bis(pyridine-2-carboxylate) dihydrate
The asymmetric unit of the title compound, C(10)H(26)N(4) (2+)·2C(6)H(4)NO(2) (-)·2H(2)O, consists of half of a doubly protonated 1,4,8,11-tetra-azacyclo-tetra-decane (cyclam) dication, a pyridine-2-carboxyl-ate anion and a solvent water mol-ecule. The complete dication is generated by a crystallographic centre and adopts an endodentate conformation which may be influenced by intra-molecular N-...

The asymmetric unit of the title compound, C(16)H(34)N(4) (2+)·2I(-)·2H(2)O, contains one half-cation, one iodide anion and one water mol-ecule. The cation has crystallographically imposed centrosymmetric symmetry. Despite some differences in the unit-cell dimensions, packing analysis on a cluster of 15 cations and a comparison of the hydrogen bonding suggests that this compound is isostructura...

The structure of the title compound, poly[triaquatetra-μ-cyanido-tetracyanidobis-(1,4,10,13-tetra-oxa-7,16-diaza-cyclo-octa-deca-ne)di-barium(II)tetra-gold(I)], [Au(4)Ba(2)(CN)(8)(C(12)H(26)N(2)O(4))(2)(H(2)O)(3)](n), displays O-H⋯N hydrogen bonding between water molecules and cyano ligands and an unusual pattern of aurophilic inter-actions that yields a monomer, dimer, and trimer of [Au(CN)(2)...
متن کامل3-Hydroxypyridinium-2-carboxylate
Comparable to many amino acids, the title compound, C(6)H(5)NO(3), is a substitution product of picolinic acid. The mol-ecule shows approximate non-crystallographic C(s) symmetry. Like many amino acids, the mol-ecule is present in its zwitterionic state. Intra- as well as inter-molecular hydrogen bonds are observed, the latter connecting the mol-ecules into zigzag chains along the crystallograp...
متن کامل2,2′-[4,10-Bis(carboxymethyl)-4,10-diaza-1,7-diazoniacyclododecane-1,7-diyl]diacetate dihydrate
In the title compound, C(16)H(28)N(4)O(8)·2H(2)O, the 12-membered macrocycle has twofold crystallographic symmetry and the asymmetric unit comprises one half-mol-ecule. The four carbox-yl/carboxyl-ate groups reside on the same side of the macrocycle. The mol-ecule is a double zwitterion with two of the carb-oxy-lic acid H atoms transferred to the two N atoms on the opposite sides of the macrocy...
