Cobalt-platinum heterometallic clusters containing N-heterocyclic carbene ligands

Abstract: The heteronuclear cobalt-platinum cluster [Co 2 Pt 2 (IPr) 2 (µ 2-CO) 4 (CO) 4 ] can be obtained through an addition reaction in [Co 2 (CO) 8 ], and with subsequent cluster fragmentation in [Co 4 (CO) 12 ] and [Co 3 (µ 3-CH)(CO) 9 ], upon reaction with the [Pt(IPr)] fragment. The last reaction also afforded another cobaltplatinum cluster [Co 4 Pt 2 (µ 6-C)(IPr) 2 (µ 2-CO) 5 (CO) 6 ]. These are the first examples of Co-Pt heteronuclear clusters containing NHC ligands.

“…For instance, the cooperativity and synergistic effects of these heterometallic compounds arisen from the simultaneous or consecutive action of their metal centers on substrates make them attractive compounds for molecular activation that mononuclear complexes are not able to achieve [4][5][6][7][8][9]. The heteropolynuclear compounds can be used as singlesource precursors for heterogeneous catalysts that offer the potential of fine-tuning their intermetallic ratio and retaining it in the resulting heterometallic particles [4,10]. Thus, understanding interactions between metals, metals and their ligand environment, and between ligands in the hetropolynuclear complexes are essential not only to their chemistry, but also to the possible application of them [11][12][13].…”

“…Внимание исследователей к гетерометаллическим комплексам и кластерам переходных металлов с мостиковыми ненасыщенными углеводородными лигандами обусловлено возможностями их применения в различных областях современной химии [1][2][3][4][5][6]. Наличие различных атомов металлов в одной молекуле делает гетерометаллические соединения более эффективными и интересными катализаторами, чем комплексы на основе одного металла [2,3].…”

“…Наличие различных атомов металлов в одной молекуле делает гетерометаллические соединения более эффективными и интересными катализаторами, чем комплексы на основе одного металла [2,3]. Кроме того, благодаря строго определенному соотношению атомов металлов в гетерометаллических соединениях они могут выступать в качестве прекурсоров полиметаллических материалов с точным распределением металлов [4]. Наиболее известные методы синтеза таких соединений основаны на взаимодействии непредельных углеводородов (алкены, алкины) с уже сформированными гетерометаллическими системами [5,6]…”
