Synthesis and crystal structure of tetracoordinated molybdenum (II) complexes containing rigid α-diimine ligands
摘要:
The complex of the general formula (dad)MoCl2 [3ai, 3bi, 3c] (dad = R'N=C(R)-C(R)=NR') is obtained in one step by reduction of [MoCl4(thf)(2)] (1) in the presence of dad ligands (dab: ai, Ar-BIAN: bi, Ph-BIC: c) (2). All new complexes have been characterized by IR and NMR spectroscopy. The X-ray single-crystal diffraction of 3a2 reveals a relatively tetrahedral coordination geometry. (c) 2005 Elsevier Ltd.
