3-Methoxycarbonyl-1-methylpyrazinium tetrachlorido(pyrazine-2-carboxylato-κ2N1,O)stannate(IV)

In the reaction of pyrazine-2-carboxylic acid and stannic chloride in methanol, one equivalent of the carboxylic acid is methylated at the 4-amino site and is also esterified, yielding the title salt, (C7H9N2O2)[SnCl4(C5H3N2O2)]. The SnIV atom in the anion is N,O-chelated by a pyrazine-2-carboxylate...

Description
Summary:In the reaction of pyrazine-2-carboxylic acid and stannic chloride in methanol, one equivalent of the carboxylic acid is methylated at the 4-amino site and is also esterified, yielding the title salt, (C7H9N2O2)[SnCl4(C5H3N2O2)]. The SnIV atom in the anion is N,O-chelated by a pyrazine-2-carboxylate in a cis-SnNOCl4 octahedral geometry.
