Primary Phosphine

We describe the coordination chemistry of the primary phosphine PH2C(O)NH2 (phosphinecarboxamide) to form the novel complexes W(CO)5(PH2C(O)NH2) (1) and cis-Mo(CO)4(PH2C(O)NH2)2 (2).

A new family of lanthanide/boron-based complexes have been synthesized from the novel substituted poly(pyrazolylpyridyl)borate ligand containing phenyl substituents on the boron atom Ph2Bppy (L). The complexes have been fully characterized by analytical and spectroscopic methods. The single crystal X-ray structure and mass spectroscopy reveal the isostructural dinuclear complexes: [Ln2(L)2(NO3)2(OH)2] where Ln = Eu, Gd or Tb. Upon excitation of the Ln(III) complexes in DCM, their luminescence spectra display narrow f–f transitions. It is found that the ligand can efficiently sensitize the Tb(III) complex because of the better triplet state energy match to the Tb(III)–5D0 excited states.

The novel tetradentate ligand N(CH2CH2CH2SH)3, H3 - 5 was synthesized from tripropanolamine via the trichloride, subsequent reaction with potassium thioacetate and reduction with LiAlH4. Ligand H3 -5 reacts with MeSnCl3 under formation of the centrosymmetric dinuclear complex [MeSn(5)]2, 6, which was shown by X-ray structure analysis to contain two tetrahedrally coordinated tin atoms and two bridging thiolato functions.

Dianionic 2,2′-diboratabiphenyl derivatives were prepared as a new class of binucleating ligands. Preliminary investigations into their coordination chemistry involved Rh complexes. Their solution and solid state structures were studied and confirm the preference for η6–η6 coordination of the novel ligands, rendering them isoelectronic analogues of the ubiquitous bicyclopentadienyl system. Comparative studies suggest stronger donor properties for the fulvalene ligand as compared with the 2,2′-diboratabiphenyl system.Key words: dinucleating ligands, bimetallic complexes, rhodium complexes, boron heterocycles, X-ray structure.
