Description

The [Ca(DMF)6][Mo6Cl14] complex (I) was synthesized by reacting octahedral cluster Mo complex (H3O)2Mo6Cl14 · 6H2O with the Ca2+ cation in DMF. Analogous reaction carried out in the presence of triphenylphosphine oxide Ph3PO in acetonitrile resulted in [{Ca(OPPh3)4}{Mo6Cl14}]∞ (II). According to X-ray diffraction data, complex I has ionic structure, while the structure of complex II consists of infinite linear chains of the cluster anionic complexes {Mo6Cl14}2- bonded to the cationic Ca complexes {Ca(OPPH3)4}2+. Both complexes exhibit intensive luminescence in red and near-IR regions of the spectrum

Abstract (Russian)

Взаимодействием октаэдрического кластерного комплекса молибдена (Н3О)2Мо6Сl14 · 6Н2О с катионом Са2+ в растворе ДМФА получено соединение состава [Са(ДМФА)6][Мо6Сl14] (I). Подобная реакция в присутствии трифенилфосфиноксида OPPh3 в ацетонитриле приводит к образованию [{Ca(OPPh3)4}{Mo6Cl14}]∞ (II). По данным рентгеноструктурного анализа, соединение I ионного типа, в то время как в структуре II образуются бесконечные линейные цепочки кластерных анионных комлексов {Мо6Сl14}2-, связанных катионными комплексами кальция {Ca(OPPh3)4}2+. Оба соединения проявляют интенсивную люминесценцию в красной и ближней инфракрасной областях спектра
