Abstract: cf. CA 58, 10812d. Both compds. crystallize in the triclinic system, probable space group ̅P. p-Me₂NC₆H₄-NCS has a 10.00, b 22.62, c 17.72 A., α 147°, β 43° 50', γ 152°; pycnometer d. = 1.12, Z = 3. p-(ClCH₂CH₂)₂NC₆H₄NCS has a 29.31, b 6.60, c 6.69 A., α 92° 40', β 100°, γ 92° 30'; pycnometer d. = 1.72; Z = 4. From mol. dimensions, calcd. on basis of ion radii, a symmetrical arrangement of 2 head-to-tail pairs of parallel planar mols. is assumed for the 2nd compd.
