^(13)C-^(15)N coupling constants in methyldimethylaminocarbene-pentacarbonyl complexes of chromium(0) and tungsten(0)

Abstract

Nuclear spin coupling constants between different kinds of nuclei, such as ^1H ^(13)C, ^(15)N,and ^(31)P are very important for structural investigations in that they provide information about the types of chemical bonding involved. In the present study, we have determined ^(13)C-^(15)N coupling constants for two methyldimethyl-aminocar-carbenepentacarbonyl complexes of chromium(0) and tungsten(0)(I and II).
