资源简介：
The reaction of Na(OSitBu2Me) with CrCl3 yields solid [Cr(OSitBu2Me)3]n (1), which can be crystallized in the presence of excess Na(OSitBu2Me) to yield [Na(THF)][Cr(OSitBu2Me)4] (2). This complex is oxidized to yield Cr(OSitBu2Me)4 (3), a crystalline chromium(IV) siloxide complex that is air- and moisture-stable. Electronic spectroscopic analysis of the absorption spectrum of 3 indicates a particularly weak ligand field (ΔT = 7940 cm–1) and covalent Cr–O bonding. 3 provides the first structural and spectroscopic characterization of a homoleptic chromium(IV) siloxide complex and provides a benchmark for tetrahedral chromium(IV) ions residing in solid oxide lattices.
