Structure and chemical bonding in cis- and trans-M(NO)2(O2CR)2 (M=Cr and Mo) complexes
摘要:
New cis- and trans-nitrosyl complexes of the formula M(NO)(2)(O2CR)(2) (M = Cr and Mo) were synthesized and characterized spectroscopically. The supporting theoretical studies indicate the deviation of molecules from their ideal geometries. The most striking consequence is the deformation of the ON-M-NO fragment from its linear form: in trans complexes. This deformation leads to the additional weak v(s)(NO) vibration.
