Crystal and molecular structure of 6-phenyl-13H-pyrimido [4,3-b:6,1-b] bis-benzothiazolium-12 triiodide
摘要:
Crystals of the synthesized title compound (C22H15I3N2S2) are monoclinic. Space group P2(1)/a, a = 15.072(2), b = 10.936(1), c = 15.363(2) angstrom, beta = 108.49(1)-degrees. The structure was solved by direct methods and refined by block-matrix least-squares procedure to give R = 0.059 and Rw = 0.043 for 3658 reflections above 2-sigma (I). The central hexaatomic ring is in a very flattened envelope conformation being the methylene group very little deviated from the plane defined by the other five atoms. The phenyl group is rotated 63.40-degrees from that plane.
