4. | Description | Abstract | Reactions of CdI2 with 2-chloro (2-ClPy), 2-bromo (2-BrPy), 2-iodo (2-IPy) and 2-bromo-5-methylpyridine (2-Br-5-MePy) led to heteroleptic neutral complexes {[LCdI2]}n (L = 2-ClPy (1), 2-BrPy (2)) and [L2CdI2] (2-IPy (3), 2-Br-5-MePy (4)); their structures were determined by single crystal X-ray diffractometry. In the structures of 3 and 4, there were found halogen bonds which were examined by DFT calculations. |
