Abstract:
The 1:1 and 2:1 reactions of (Me(3)Si)(2)PLi.2THF with several amino chlorophosphanes have been surveyed. With (i)()Pr(2)NPCl(2), both reactant stoichiometries produce the four-membered ring compound (3) via different reaction schemes. Compound 3 combines with Fe(2)(CO)(9) to produce a monometallic complex (4) in which the Fe(CO)(4) fragment is bonded to one of the Me(3)SiP centers. With the cyclic hydrazino phosphane ClP(MeNNMe)(2)PCl only the bis-phosphane substitution product, (Me(3)Si)(2)PP(MeNNMe)(2)PP(SiMe(3))(2), is isolated. With the cyclic diazadiphosphetidine ((t)()BuNPCl)(2) a bis-phosphane substitution product [(t)()BuNPP(SiMe(3))(2)](2) (10) is formed along with a cage compound [((t)()BuNP)(2)P(SiMe(3))](2) (11). The new compounds have been characterized by spectroscopic techniques, and the molecular structure of 4 and 11 have been determined by X-ray crystallography.

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 be...
