Synthesis and Crystal Structure of the [Ni_(32)C_6(CO)_(36)]~(6-) Hexaanion: An Extended Fragment of the M_(23)C_6 Lattice Stabilized in a Shell of Edge-Bridging Carbonyl Ligands

摘要

Transition metal carbonyl clusters of high nuclearity are often closely related to fragments of a metal lattice; more rarely, clusters that can be considered as an extended fragment of the lattice of a binary compound have been stabilized in a ligandshell, although some important examples of this type of cluster are known. Metal carbonyl clusters that exhibit the above behavior are of interest since they may provide a molecular approach to new materials, and may be used as models for both experimental and theoretical studies.
