Tris(5-acetyl-3-thienyl)methane (TATM) forms an inclusion compound wit
h cyclononanone in a host/guest ratio of 1/1, C19H16O3S3.C9H16O. The c
rystal belongs to the monoclinic system. The cavity formed by the TATM
molecule is of a zigzag-channel type, parallel to the c axis. The cyc
lononanone guest molecule occupies two orientationally disordered posi
tions with occupation factors of 25 and 75%. The two cyclononanone mol
ecules each have the (g(-)g(-)ggg(-)g(-)sg(-)s) conformation.
