Abstract Two novel copper (I) π-complexes containing the SiF 6 2− anion have been synthesized and studied by X-ray structure analysis. The crystals of the first title compound (A) are monoclinic, space group P21/b with a=13.039(5), b=10.586(4), c=6.072(2) Å, γ=100.23(2)°, and Z=2. The crystals of the second title compound (B) are triclinic, space group $$P\bar 1$$ with a=14.495(5), b=7.633(2), c=6.429(8) Å, α=90.67(8), β=81.80(8), γ=94.05(3)°, and Z=1. In structure A, the copper cations and the bridge formiate anions form infinite [Cu(HCOO)]n spirals, which are cross-linked due to the π-interaction between copper and the double bond AA and the strong hydrogen bonds N−H... F(SiF 6 2− ) to form a three-dimensional framework. In structure B, allylammonium similarly acts as a bridge linking the SiF 6 2− and Cu4Cl 6 2− anions into layers.
