Reactions of the aminoiminophenols 2-((2-(dimethylamino)ethylimino)methyl)phenol (HL(1)) or 2-{(3-(dimethylamino)propylimino)methyl}phenol (HL(2)) with nickel(II) chloride, K(2)[PtCl(4)] or copper(II) acetate in alcoholic solution, in the absence or in the presence of sodium azide, afford the corresponding new mononuclear complexes [M(L(1))(X)(H(2)O)(n)] [M = Ni, X = Cl(-), n = 2 (); M = Ni, X ...

reaction of glycin with malononitrile afforded respective pyrrole. pyrrole is one of the heterocyclic compounds with very important biological activities. heterocycles are extremely important because of their wide range of applications that goes from their use as pharmaceuticals and agrochemicals to dyestuffs and additives. in this view, it was proposed to synthesize pyrrole-3-carbonitrile deri...

In the title salt, C(5)H(6)BrN(2) (+)·C(7)H(6)NO(2) (-), the pyridine N atom of the 2-amino-5-bromo-pyridine mol-ecule is protonated. In the crystal, the protonated N atom and the 2-amino group are hydrogen-bonded to the carboxyl-ate O atoms via a pair of N-H⋯O hydrogen bonds, forming an R(2) (2)(8) ring motif. Two inversion-related 3-amino-benzoate anions are linked through N-H⋯O hydrogen-bond...

In the title compound, C(8)H(12)N(2)O(3)S·H(2)O, inter-molecular O-H⋯O and N-H⋯O hydrogen bonds and weak C-H⋯O inter-actions, which form R(1) (2)(6) and R(2) (2)(12) ring motifs, link the components into a three-dimensional network.

In the title salt, C(6)H(9)N(2) (+)·C(7)H(4)ClO(2) (-), the 2-amino-4-methyl-pyridinium cation is almost planar, with a maximum deviation of 0.010 (1) Å. In the crystal, the protonated N atom and the 2-amino group of the cation are hydrogen bonded to the carboxyl-ate O atoms of the anion via a pair of N-H⋯O hydrogen bonds, forming an R(2) (2)(8) ring motif. The ion pairs are further connected v...
