摘要：

The X-ray crystal structure of propargylammonium hexafluorosilicate, 2(C3H6N)+ (SiF6)2−, is determined. The SiF6 anion is involved in N−H...F and C−H...F interactions with eight surrounding cations. This involves two-three-and four-center N−H...F hydrogen bonds, and additional C−H...F interactions with C...F distances down to 2.963(6) Å. The alkynyl C−H donors form only C−H...F interactions of unfavorable geometries.
