Abstract:

The transition metal complexes with phosphido bridge have been widely used in synthesis of organometallic compounds. The NMR 31P chemical shift is useful in structure elucidation. The value of 31P shift often used as a structural probe for the presence or absence of metal-metal bond. In this paper, the 31P shift of the series of compound [(CO)4M(μ-PMe2)]2, M=V, Cr, Mn have been calculated. The correlation of 31P shift with metal-metal bond has been studied.
In this paper "Magnetic nuclei molecular orbit group approximation for calculation of NMR chemical shift" has been proposed.
