Abstract: Crystal structures of the title compounds, [Mn(N3)2(phen)2] (1), [Co(N3)2(phen)2] (2) and [Cu(N3)2(phen)2]∙1.5 H2O (3), have been determined at 100 K. Central atoms of the above- mentioned compounds are coordinated by four pyridine nitrogen donor atoms from two 1,10-phenanthroline molecules and two nitrogen donor atoms of terminally coordinated azide anions, which resulted in a distorted {MN6} octahedral geometry. The π-π stacking interactions, as well as weak C—H∙∙∙N hydrogen bonds, were observed in all three compounds. Moreover, complex 3 revealed also supramolecular chains of the complex and water molecules linked together through O—H∙∙∙N hydrogen bonds.

Keywords: azide anions, crystal structures, hydrogen bonds, 1,10-phenanthroline, p-p stacking interactions
