The concept of bond-stretch isomerization was a debated topic in the inorganic literature throughout the 1970's and 1980's. The best example of this concept is that of mer- MOOCI2(PMe2Ph)3. Single crystal XRD showed two unique bond distances for the M=O double bond and IR data showed two unique stretching frequencies, suggesting that two isomers of the complex existed with two unique M=O bond distances. However, this idea didn't sit well with many inorganic chemists as it seemed to defy our understanding of chemical bonding. In the 1990's, the concept of bond-stretch isomers was finally debunked with the help of higher resolution instrumentation. Read Gerard Parkin's Acc. Chem. Res. article on the topic and explain how XRD, IR, and 'H-NMR experiments were used in combination to unravel the mystery.

Question
The concept of bond-stretch isomerization was a debated topic in the inorganic literature throughout the 1970’s and 1980’s. The best example of this concept is that of mer-MoOCl₂(PMe₂Ph)₃. Single crystal XRD showed two unique bond distances for the M=O double bond and IR data showed two unique stretching frequencies, suggesting that two isomers of the complex existed with two unique M=O bond distances. However, this idea didn’t sit well with many inorganic chemists as it seemed to defy our understanding of chemical bonding. In the 1990’s, the concept of bond-stretch isomers was finally debunked with the help of higher resolution instrumentation. Read Gerard Parkin’s *Acc. Chem. Res.* article on the topic and explain how XRD, IR, and ¹H-NMR experiments were used in combination to unravel the mystery.
