2-Amino-5-methyl-pyridinium dibromo-iodate.

ABSTRACT: In the title salt, C(6)H(9)N(2) (+)·Br(2)I(-), the cation is essentially planar (r.m.s. deviation = 0.0062?Å for the non-H atoms) while the anion is almost linear with a Br-I-Br angle of 177.67?(2)°. The crystal packing shows two anions and two cations connected via N-H?Br and (pyridine)N-H?Br hydrogen-bonding inter-actions, forming centrosymmetric tetra-mers with R(4) (4)(16) ring motifs. Very weak offset aromatic ?-? stacking interactions [centroid-centroid separation = 4.038?(4), slippage = 1.773?Å] also occur.

2-Amino-5-methyl-pyridinium 4-methyl-benzoate.

Project description:The 4-methyl-benzoate anion of the title salt, C6H9N2(+)·C8H7O2(-), is nearly planar, with a dihedral angle of 6.26?(10)° between the benzene ring and the carboxyl-ate group.

Project description:In the asymmetric unit of the title salt, C6H9N2 (+)·C7H7O3S(-), there are two independent 2-amino-6-methyl-pyridinium cations and two independent 4-methyl-benzene-sulfonate anions.
