Abstract
A new complex of 2-aminopyridine and malonic acid in a 1:1 stoichiometric ratio is obtained. The complex crystallizes in a centrosymmetric P21/c space group with a = 3.8522(2) Å, b = 17.5226(8) Å, c = 13.7317(7) Å and β = 94.418(3)°. This complex is held by network of hydrogen bonds between the protonated 2-aminopyridinium cation and the malonate anion. There is no phase transition observed in this complex, which is verified using DSC and single crystal X-ray measurement studies. Unlike 2-aminopyridinium maleate, this complex crystallizes in the centrosymmetric space group and hence, this complex will not exhibit any non-linear optical property.
