4-fluorophenylpyridine, respectively. Single crystal X-ray diffraction study on 1a revealed existence of two trans-N,N′ cyclometalates, with both chloride and dpnH donors located at the positions opposite to the phenyl substituents. Subsequent heating of 1a−1c at higher temperature afforded the second isomer (2a−2c), showing formation of cis-N,N′ orientation for the aforementioned cyclometalates. Further thermolysis
