Spontaneous Association of the Terbium Cyclopentadienyl Complexes under Controlled Hydrolysis

Аннотация

Controlled hydrolysis of the terbium cyclopentadienyl complexes results in the formation of the heteroligand tetranuclear terbium complex [{Tb(η⁵-C₅H₅)}₃{Tb(THF)₃}(μ₃-Cl)(μ₂-Cl)₆(μ₄-O)] (I), the recrystallization of which from tetrahydrofuran (THF) gives solvatomorph I · 0.5THF (Ia). According to the X-ray structure analysis data (CIF files CCDC 1569329 (I) and 1569330 (Ia)), the complexes are tetrahedral with the μ₄-bridging O^2– anion at the center of the tetrahedron. The cyclopentadienyl ligand in complex I is shown to act as an “antenna” providing luminescence of the complex.
