Abstract:
From the reaction of [Nb6 I11 ] with 2-aminoethanol in pyridine the cluster compound [Nb6 (OC2 H4 NH2 )12 ]I3 has been obtained and the single-crystal X-ray structure determined. It represents the first example of a group VB metal cluster compound with hexanuclear, octahedral metal atom core, which carries intra-cluster chelate ligands. With the formation of this unprecedented cluster cation we report for the first time a transformation of a 6-8 to a 6-12 type cluster unit. The formation of the cluster cation goes along with a one-electron oxidation of the cluster starting material. Furthermore, it adds a second entry to the so far very small group of M6 cluster compounds with organic ligands on the inner cluster sites.

Cluster Sampling Method
To choose a cluster sample, divide the population into clusters (groups) and then randomly select some of the clusters. All the members from these clusters are in the cluster sample. For example, if you randomly sample four departments from your...

Metal-Ligand Bonds
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...

Ligand Binding Sites
Protein-ligand interactions are quite specific; even though numerous potential ligands surround a cellular protein at any given time, only a particular ligand can bind to that protein. Moreover, a ligand binds only to a dedicated area on the surface of the protein, known as the...
