Abstract

UV-vis spectrum: X,, c~~ c'z 250 nm, sh (log e 4.11), 265 (4.29), 360 inn (4.04). 375 (4.04), 379 sh (4.01), 443 (4.36), 523 br (2.79), 553 (2.81); kcsz 533 (2.55), 562 (2.66), 633 br (1.94), 681 (1.92). The planar molecules form stacks parallel to the c-axis with the S= CSC= S moiety sandwiched between the naphthalene units along the stacks. There are no unusual intermolecular contacts. The distortion of the naphthalene unit is small and not ...
