Bimetallic cyclooligosiloxanolate complexes of copper and nickel

Bis(μ6-cis-2,4,6,8,10,12,14,16-octamethylcyclooctasiloxane-2,4,6,8,10,12,14,16-octolato)octakis[(dimethylformamide)copper(II)] dimethylformamide solvate enclosing a pyrazine molecule

“…In recent years, the synthesis of metallaorganosiloxane compounds has attracted much attention due to the molecular magnetism of these compounds. A series of new crystalline copper-containing organosiloxanes has been synthesized and structurally characterized (Lindeman et al, 1997;Zucchi et al, 2000;Molodtsova et al, 1998;Abbati et al, 2003;Zucchi et al, 1998). We report here the structure of the title novel polyhedral methylsiloxane complex, (I), containing eight Cu atoms, with an encapsulated molecule of pyrazine.…”

Well-defined cyclic silanol derivatives

“…Since the early 1990s, a set of cage-like metallasiloxanes involving alkaline metals, Cu, Ni, Mn, Ln, etc. have been developed [96][97][98][99][100][101][102][103][104] and they constitute the most utilized precursors for the preparation of MOSSs. In most cases, the cage-like organometallasiloxanes were treated with triorganochlorosi-Scheme 13 Synthesis of BODIFY-functionalized derivative 95.…”

Carborane–Siloxanes: Synthesis and Properties. New Possibilities for Structure Control

“…In particular, along with the cubic carborane-containing structures, cyclosiloxanes can be considered as promising molecular fillers. The synthesis of these compounds was carried out using individual organometallosiloxanes [86][87][88][89][90][91][92][93][94][95][96][97][98][99]; investigations on their synthesis and properties are actively developed at the Laboratory of Organosilicon Compounds, INEOS RAS.…”
