Functionalized Tripod Ligands: Synthesis and Coordination of 1,1,1-Tris[(diphenylphosphanyl)methyl]methaneThe tripod ligand HC(CH2PPh2)3 (4) is easily available from the reaction of 1,3-dichloro-2-(chloromethyl)propane (3) with lithium diphenylphosphide. The ligand 4 itself and two of its coordination compounds, [(HC(CH2PPh2)3)Co(OOCMe)]+-[BPh4]- (5 · BPh4) and [(HC(CH2PPH2)3)Co(OOCMe)]2+ · 2[BF4]- [7 · (BF4)2] have been characterized by X-ray analyses. Coordination of 4 leads to an opening of the CH2—CH—CH2 bond angles (114° in 7 · (BF4)2 and 5 · BPh4 versus 111° in 4). This change in structure is reflected by the unusual low field shift of the methine hydrogen of 7 · (BF4)2 (δ = 3.90) in comparison with the corresponding signal of the free ligand 4 (δ = 1.53).
