ABSTRACT: The matrix isolation technique has been combined with infrared spectroscopy to identify and characterize the product of the codeposition of CH3ReO3 with NH3 into inert matrices at 14 K. This codeposition led to the formation of the isolated 1:1 complex between these two reagents and its isolation in argon and nitrogen matrices. The complex is characterized by perturbations to all of the vibrational modes of the NH3 subunit in the complex, including a large, 185 cm(-1) blue shift of v2, the symmetric deformation mode. In addition, shifts of the -ReO3 antisymmetric stretch and -ReO3 symmetric bending of the CH3ReO3 subunit in the complex were observed. This complex, while predicted theoretically, has not been reported previously.
