Two new mononuclear gold(I)-nitrogen [N,N′-di(2,6-methyl)phenylformamidine] complexes: Syntheses and crystal structures

Two gold(I) mononuclear complexes have been prepared by reacting gold(I) tetrahydrothiophene with N,N′-di(2,6-methyl)phenylformamidine. The neutral complex N,N′-di(2,6-methyl)phenylformamidine)-gold(I) chloride (C₁₇H₂₀AuClN₂) (1), crystallizes in the triclinic group while the cationic N,N′-di(2,6-methyl)phenylformamidine](tetrahydrothiophene)-gold(I) (C₂₁H₂₈AuN₂S) (2) crystallizes with a nitrate anion in the monoclinic group P2(1)/n. Both compounds are good starting materials for synthetic gold chemistry.
