| Popis: | Two coordination compounds copper(II) with tetrafluoridoborate as the anion and [1,2,4]triazolo[1,5-a]pyrimidine (abbreviated as tp) as the ligand are presented, together with their crystal structure and spectroscopic properties. A light blue compound [Cu(tp)4(H2O)2](BF4)2(CH3OH) (1) with a tetragonal chromophore and a dark blue compound [Cu(tp)5](BF4)2(CH3OH) (2) are formed from the same batch. Compound (2) has a quite unusual geometry for Cu(II) with just 5 tp ligands, homoleptically coordinated to the metal ion. Both compounds show interesting hydrogen-bond interactions in the solid state, where coordinated water is intramolecularly bound to non-coordinated N atoms of tp (in 1), and methanol is attached to the anion (in 2). Cu(II) coordination compounds with the [1,2,4]triazolo[1,5-a]pyrimidine ligand are reported, including, the [Cu(tp)5] cation with for Cu(II) just 5 tp ligands, homoleptically coordinated to the metal ion. |
