Family of Polynuclear Nickel Cagelike Phenylsilsesquioxanes; Features of Periodic Networks and Magnetic Properties

A new family of bi-, tetra-, penta-, and hexanickel cagelike phenylsilsesquioxanes 1–6 was obtained by self-assembly and transmetalation procedures. Their crystal structures were established by single-crystal X-ray analysis, and features of crystal packing relevant to the network formation were stud...

Description
Summary:A new family of bi-, tetra-, penta-, and hexanickel cagelike phenylsilsesquioxanes 1–6 was obtained by self-assembly and transmetalation procedures. Their crystal structures were established by single-crystal X-ray analysis, and features of crystal packing relevant to the network formation were studied by a topological analysis. Compounds 1, 2, and 4 are isolated architectures, while 3, 5, and 6 present extended 1D and 3D networks. The investigation of magnetic properties revealed the presence of ferro- (1 and 3–5) or antiferromagnetic (2 and 6) interactions between Ni­(II) ions, giving rise in the most cases (1, 2, and 4–6) to the presence of a slow relaxation of the magnetization, which can originate from the spin frustration.
