A series of new molecular complexes C60(S4N4)2-x(C6H6)x:: Synthesis, X-ray study of crystal structure and structural disorder

The reaction of C-60 with tetrasulfur tetranitride donor in benzene yielded a continuous series of molecular complexes: C-60(S4N4)(2-x)(C6H6)(x). The study of the crystal structure of tie compound with x = 0.67 reveals it to have a layered structure with alternating sheets of densely packed C-60 molecules and the sheets of the donor and benzene molecules. A statistic disorder of S4N4 and C6H6 molecules in one of two positions of guest molecules was found. (C) 1997 Elsevier Science Ltd.
