Self assembly of silver(I) coordination polymers formed through hydrogen bonding with a new ditopic heteroscorpionate ligand

The new ditopic heteroscorpionate ligand, (3-methoxy-4-hydroxyphenyl)bis(3,5-dimethyl-pyrazolyl)methane (L5v), and four coordination polymers of silver Ag(I) derived therefrom, have been synthesized and characterized by X-ray diffraction, ESI-MS, IR spectroscopy and elemental analysis. The presence of different anions (i.e. BF4-, CF3SO3-, NO3-, or SbF6-) lead to different crystal packing schemes due to different H-bonding patterns that depend on the relative charge delocalization and/or shape of the anion.
