Manganese Carbonyl

Manganese carbonyl complexes bearing dibenzophospholyl (DBP) and 1-phenyldibenzophosphole (Ph-DBP) ligands have been prepared. Reaction of Li-DBP with Mn(CO)5Br gave (µ2-DBP)(µ2-Br)Mn2(CO)8, while reaction of bis(1,1'-dibenzophospholyl) and Mn2(CO)10 yielded (µ2-DBP)2Mn2(CO)8. The phosphine adducts (Ph-DBP)Mn2(CO)9 and (Ph-DBP)2Mn2(CO)8 were obtained by reaction of Ph-DBP and Mn2(CO)10. The ligands are σ-bonded through the phosphorus atom in all complexes. The compounds were characterized by 1H, 13C, and 31P NMR and IR spectroscopy, mass spectrometry, and X-ray diffraction.Key words: dibenzophospholyl, dibenzophosphole, manganese, heterocycle.

The solvothermal combination of trivalent lanthanide metal precursors with a squarate ligand (H2C4O4, 3,4-dihydroxy-3-cyclobutene-1,2-dione) has afforded the preparation of a family of eight new coordination polymers, [Ln2(C4O4)3(H2O)4] (Ln = La–Nd, Ho) (1–5), [Ln2(C4O4)3(H2O)8] (Ln = Er, Dy) (6, 7), and Tb2(C4O4)2(C2O4)(H2O)4 (8). Structural analysis reveals that the squarate ligand displays versatile coordination modes to generate novel 2D and 3D frameworks. Three new coordination modes, a bidentate/monodentate μ3 and two bidentate/monodentate μ4 coordination modes, are first reported. In addition, the variable-temperature magnetic properties of the Pr, Nd, Ho, Dy, and Tb complexes, the solid-state near-infrared luminescence spectra of the Pr, Nd, Ho, and Er complexes, and their thermogravimetric analyses are discussed.
