The reaction of [Zn(NH$_3$)$_4$]$^{2+}$ in aqueous ammonia solution with quinaldinic acid (quinoline-2-carboxylic acid) gave a mononuclear heteroleptic ammine/quinaldinate complex with the [Zn(quin)$_2$(NH$_3$)] composition. The introduced secondary ligand adopted the usual N,O-bidentate chelating coordination. In the analogous reaction with pyrazinoic acid (pyrazine-2-carboxylic acid), complete substitution of ammonia with pyrazionate and water was observed. A mixture of two compounds formed: a mononuclear and already known [Zn(pyraz)$_2$(H$_2$O)$_2$] and a novel one-dimensional (1D) coordination polymer [Zn(pyraz)$_2$(H$_2$O)]$_n$. X-ray structure analysis revealed the pyrazinoate ligands in [Zn(pyraz)$_2$(H$_2$O)]$_n$ in two binding modes, in a bidentate chelating coordination and in a tridentate bridging coordination. The bridging pyrazinoate has engaged in binding three out of four donors: a carboxylate oxygen and both nitrogen atoms. A detailed presentation of the structure of [Zn(pyraz)$_2$(H$_2$O)]$_n$ and its comparison with the structures of related compounds are given below.
