چکیده
In the title compound, C(6)H(9)N(2) (+)·C(7)H(4)NO(4) (-)·H(2)O, one amino group of diamino-benzene is protonated while one carb-oxy group of pyridine-2,6-dicarb-oxy-lic acid is deprotonated. In the anion, the CO(2) and CO(2)H groups make dihedral angles of 4.0 (5) and 8.7 (4)° with the pyridine ring. In the crystal, extensive N-H⋯O, N-H⋯N and O-H⋯O hydrogen bonds occur between anions, cations and water mol-ecules.

In the title compound, C(6)H(9)N(2) (+)·C(6)H(2)N(3)O(7) (-), the three nitro groups of the anion are twisted from the central benzene ring at dihedral angles of 5.4 (1), 27.1 (1) and 32.9 (1)°. In the crystal, inter-molecular N-H⋯O, N-H⋯(O,O) and N-H⋯N hydrogen bonds link the cations and anions into layers parallel to the bc plane.

In the crystal structure of the title compound, C(6)H(9)N(2) (+)·ClCH(2)COO(-), prepared by the reaction of OPDA (orthophenelynediamine) with chloro-acetic -acid, N-H⋯O hydrogen bonds generate ladder-like chains and very weak inter-molecular C-H⋯Cl hydrogen-bonding inter-actions between the anions and cations lead to a supra-molecular network. C-H⋯O inter-actions also occur.

Although 6-azido-6-de-oxy-l-galactose in aqueous solution is in equilibrium between the open-chain, furan-ose and pyran-ose forms, it crystallizes solely as 6-azido-6-de-oxy-α-l-galactopyran-ose monohydrate, C(6)H(11)N(3)O(5)·H(2)O, with the six-membered ring adopting a chair conformation. The structure exists as hydrogen-bonded chains, with each mol-ecule acting as a donor and acceptor of five...
