Abstract

The [{Re₆Te₈}(imzH)₆]²⁺ cationic cluster complex prepared by the interaction of [{Re₆Te₈} (TeI₂)₆]I₂·[{Re₆Te₈}(TeI₂)₄(TeI₃)₂]·I₂ with imidazole (imzH) in a sealed glass ampoule at 200 °C for 48 h. The composition of the obtained compound is confirmed by ¹H NMR spectroscopy and high-resolution mass spectrometry. The single crystals suitable for SC-XRD are prepared by slow diffusion of diethyl ether vapors into a solution of the complex in DMF. According to the SC-XRD data, the resulting complex has the composition [{Re₆Te₈}(imzH)₆]I₂·2/3DMF. The compound crystallizes in the monoclinic crystal system, P2₁/c space group, with the following unit cell parameters: a = 18.0379(4) Å, b = 17.9945(5) Å, c = 33.1318(7) Å, β = 115.1829(10)°, V = 9732.0(4) Å³, Z = 6. It is also shown that this compound exhibits solid-state luminescence with an emission maximum at 730 nm characteristic of octahedral rhenium cluster complexes.
