Abstract
[Co(im)6] · (SiF6) · (im)2 (1) and cis-[Cd2(bipy)2(H2O)4(μ-F)2] · SiF6 (2) [im = imidazole, bipy = 2,2'-bipyridine] have been synthesized and characterized by elemental analysis, IR, UV spectra, and single crystal X-ray diffraction. Crystal data show that two compounds are octahedral and compound 2 is cis. Compound 1 displays a layer structure and [image omitted] bridging hexagram formation by N-H ··· F-Si interactions between imidazole and [image omitted]. Compound 2 has two Cds connected by μ-F and O-H ··· F-S resulting in cave conformation with π-π interactions. For both compounds, [image omitted] plays an important role in assembling the supramolecular aggregates. The thermal stabilities have also been investigated.
