Novel Cobalt‐ and Nickel‐Clusters with S and PPh3 as Ligands; Crystal Structures of [Co7S6(PPh3)5Cl2], [Co6S8(PPh3)6]+[CoCl3(THF)]−, [Ni8S6Cl2(PPh3)6], and [Ni8S5(PPh3)7]

A cube lacking one corner is one way to describe the structure of the cluster 1, which can be prepared from [CoCl2 (PPh3)2] and S(SiMe3)2 in tetrahydrofuran. All Co atoms are coordinated in a distorted tetrahedral fashion, either by three S atoms and the P atom of the PPh3 ligand or by three S ligands and a Cl ligand.
