Abstract:
This paper reports the synthesis of the first series of terminal phosphido Ni(II) complexes supported by the β-diketiminato ligand [PrNN] (where PrNN = 2,4-bis(2,6-diisopropylphenylimido)pentyl). Neutral mononuclear Ni(II) complexes [PrNN]Ni-PPh2 (2) and [PrNN]Ni-PAd2 (3) were obtained from the reaction of [PrNN]NiBr2Li(thf)2 (1) with the R2PM (R = Ph, 1-adamantyl (Ad); M = Li, K) phosphide reagents. The structures of the synthesized compounds were determined by single-crystal X-ray diffraction, which revealed that the Ni center in these terminal phosphido complexes is three-coordinate with an almost planar geometry when R = Ph and a pyramidal geometry when R = Ad. The reactivity of the synthesized complexes was also studied in a range of bond forming reactions, including P-C and P-P bonds.

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...
Structural Isomerism
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can...
Colors and Magnetism
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...
