Abstract

Chemical preparation, X-ray single crystal, thermal analysis and IR spectroscopic investigation of (C₇H₁₀N)₂ SO₄ denoted NMAS are described. The NMAS crystallizes in the triclinic system with P-1 space group. Its unit cell dimensions are a = 9.6150(5) Å, b = 9.9744(3) Å, c = 10.2767(6) Å, α = 68.069(3)°, β = 62.929(2)°, γ = 67.285(3)° with V = 785.72(7) ų and Z = 2. The structure has been solved using direct method and refined to a reliability R factor of 3.62%. The NMAS structure is built up from chains containing all the components of the structure and parallel to the b axis, linked via N—H­­­­­···O hydrogen bonds. Stability between successive chains is performed by weak interactions originating from the organic cations.
