Abstract
To vary the substitution pattern of 1,2,4-triphospholyl ligands, K[P(3)C(2)Mes(2)] (Mes=2,4,6-trimethylphenyl), bearing two bulky mesityl ligands, was synthesized. Subsequent reaction with [FeBr2(dme)] and LiCp* results in the formation of the corresponding triphosphaferrocene [Cp*Fe(eta(5)-P(3)C(2)Mes(2))] (1) in very good yields.

Abstract
To vary the substitution pattern of 1,2,4-triphospholyl ligands, K[P(3)C(2)Mes(2)] (Mes=2,4,6-trimethylphenyl), bearing two bulky mesityl ligands, was synthesized. Subsequent reaction with [FeBr2(dme)] and LiCp* results in the formation of the corresponding triphosphaferrocene [Cp*Fe(eta(5)-P(3)C(2)Mes(2))] (1) in very good yields. P-31{H-1} NMR investigations reveal a temperature depending behavior of the chemical shifts of 1. The X-ray structural analysis exhibits an eclipsed sandwich compound.
