Tetra­kis(134679-hexa­aza-1H-phen­alen-6-ium) sodium(I) penta­kis(tetra­fluorido­borate)

摘要

In the title compound, Na⁺·4C7H5N6 ⁺·5BF4 ⁻, the Na⁺ ion lies on a fourfold rotation axis and one of the tetra­fluoridoborate ions lies on a site of symmetry . Each Na⁺ ion is surrounded by four symmetry-related tetra­fluoridoborate ions, and is eight-coordinated by F atoms, the Na⋯F separation being 2.3956 (15) or 2.4347 (17) Å. The hexa­azaphenalenium ring system is essentially planar. In the crystal structure, the cations and anions are linked into a three-dimensional network by N—H⋯N and C—H⋯F hydrogen bonds.
