One‐dimensional coordination polymers based on first‐row transition metals: A solid‐state study of weak backbone interactions

Abstract

AbstractWe present further data on the solid‐state structures of one‐dimensional coordination polymers based upon dipositive transition metal hexafluoro‐acetylacetonate (hfacac) complexes. A variety of linking subunits are employed in order to investigate and probe the relatively weak interactions that make up the backbones of these polymers. Reported in this study are metal complexes containing manganese, zinc, copper, and cobalt and a range of donor building blocks encompassing an array of bonding motifs, including pyridyl—metal, pyridyl(N‐oxide)—metal, and hydrogen bonding. The specific linkers utilized are 4,4′‐dipyridyl N,N′‐dioxide hydrate, 2,5‐bis(4‐ethynylpyridyl)furan, 4,4′‐trimethylenedipyridine, and trans‐1‐(2‐pyridyl)‐2‐(4‐pyridyl)‐ethylene. A detailed discussion of the products is presented, as is a comparison to known compounds of a similar nature. All compounds are characterized via single‐crystal X‐ray diffraction and elemental analysis for the bulk of the sample.
