| Abstract: | Heteroligand coordination compounds Ln(Dbm)2HL · nEtOH, where Ln is Nd(III), Yb(III), and Er(III); HDbm is dibenzoylmethane; H2L is bis(5-pyridin-2-yl-1,2,4-triazol-3-yl)methane, are synthesized and studied. The complexes are studied by elemental analysis, TGA, and IR spectroscopy. The structure of complex [Nd(Dbm)2 · HL · EtOH] · EtOH is determined by X-ray diffraction analysis. The crystals are triclinic, space group $Pbar 1$ , a = 10.2004(9), b = 11.3809(10), c = 20.9173(18) Å, α = 102.133(1)°, β = 103.568(1)°, γ = 100.306(2)°; Z = 2 (8416 reflections with I > 2σ(I), R = 0.053, Rw = 0.136). The luminescence of solid samples of the studied complexes is studied in the near-IR region. |
