Sažetak
Cyanometallate anions such as hexacyanoferrate or hexacyanocobaltate are Lewis bases and are therefore good hydrogen [1] and halogen bond [2] acceptors. Protonated cyanometallate anions, such as hexacyanoferrates, are good hydrogen bond donors.[3] Protonated hexacyanoferrates have recently also been studied as potential halogen bond donors.[4] To the best of our knowledge, no similar studies have been performed with other protonated cyanometallates to date. In this work we have used hexacyanocobaltate(III) acid (H3[Co(CN)6]) with 2-chloropyridine (2-Clpy), 2- bromopyridine (2- Brpy) and 2-iodopyridine (2-Ipy) to synthetize three salts. In all three cases I∙∙∙N halogen bonds and N-H∙∙∙N hydrogen bonds are present, along with O-H∙∙∙N hydrogen bonds between the anions and Zundel (H5O2+) cations. The anion is completely deprotonated in all three salts. 2- Clpy and 2-Brpy salts are isostructural, while the 2-Ipy salt contains a tetramer of water molecules bridging six hexacyanocobaltate(III) anions and two 2-IpyH cations.
