O. Cox et al., CRYSTAL AND MOLECULAR-STRUCTURE OF AHYDRO-5H-BENZOCYCLOHEPTEN-5-YLIDENE)ETHANONITRILE, Journal of crystallographic and spectroscopic research, 23(10), 1993, pp. 825-828
The title compound C20H16N2S is crystallized in the monoclinic space g
roup P2(1)/c with cell parameters a = 10.663(4), b = 17.585(9), c = 9.
418(5) angstrom, beta = 115.23-degrees-(4), V = 1598(3) angstrom3, Z =
4. The structure was refined by full-matrix least-squares methods usi
ng X-ray data set collected at room temperature. A final R(F) = 0.033
and R(w) = 0.048 for 2225 unique reflections with I > 3sigma(I) and 27
2 variables was obtained. The X-ray crystallographic study establishes
the Z stereochemistry of the title compound.
