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 P 1 ¯ 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.
