A new complex C_(18)H_(24)CoF_6N_(12)Si has been synthesized by the reaction of cobalt(II) fluoride tetrahydrate with imidazole in a glass vessel. SiF_6~(2-)was generated by in situ reaction of fluoride on silica. This complex has been characterized by different techniques such as elemental analysis, IR studies, magnetic measurements, electronic absorption measurements and single-crystal X-ray structure determination. The crystals are hexagonal in the R-3 space group, with a = 13.225(6), b = 13.225(6), c = 12.517(11) ?, and g = 120°. In complex [Co(im)_6]SiF_6, the cobalt atom is six-coordinated to adopt a regular octahedral geometry and the SiF_6~(2-)ion acts as the counter anion. The crystal displays a network structure and SiF_6~(2-) bridging hexagram formation by N-(39)···F-Si interactions between imdazole and SiF_6~(2-). SiF_6~(2-)plays an important role in assembling the supramolecular aggregates.
