Description

Yttrium complexes of the composition [LY(thf)(μ-Cl)]2 · 4thf (1 · 4thf) and [LY(thf)3]+[L2Y]- (2), where LH2 5,11,17,23-tetra-tert-butyl-25,27-dihydroxy-26,28-dimethoxycalix[4]arene, were synthesized in tetrahydrofuran (thf) medium. According to X-ray diffraction analysis data complex 1 has a dimeric structure. Atom of Y has coordination number 7, ir coordinates four O atoms of the calixarene fragment, atom of O in thf molecule and two bridge atoms of Cl. Compound 2 is a ionic complex, where Y atoms coordinate three thf molecules and calixarene ligands

Abstract (Russian)

В среде тетрагидрофурана (thf) синтезированы комплексы иттрия состава [LY(thf)(μ-Cl)]2 · 4thf (1 · 4thf) и [LY(thf)3]+[L2Y]- (2), где LH2 5,11,17,23-тетра-трет-бутил-25,27-дигидрокси-26,28-диметокси-каликс[4]арен. По данным рентгеноструктурного анализа комплекс 1 имеет димерную структуру. Атом Y имеет координационное число 7 и координирует четыре атома О каликсаренового фрагмента, атом О молекулы thf и два мостиковых атома Cl. Соединение 2 представляет собой ионный комплекс, в котором атомы Y координируют три молекулы thf и каликсареновые лиганды
