The inclusion complexes formed from carbon disulfide and p-tert-butylcalix[4]arene ( 1·CS2) or p-tert-butylcalix[6]arene (2·CS2) were investigated by X-ray crystal structure analysis, infrared (IR) and Raman spectroscopy. The complex 1·CS2 crystallises in the space group P4/n, 2·CS2 in the space group P21/n. In case of p-tert-butylcalix[4]arene as host the carbon disulfide molecule is included in the cavity. In the crystal structure of p-tert-butylcalix[ 6]arene clathrate, self-complexation of one tert-butyl group in the cavity of another calix[ 6]arene can be observed. Due to inclusion, the symmetry of CS2 is lowered both in the p-tert- butylcalix[4]arene and p-tert-butylcalix[6]arene case causing significant shifts in the fully assigned infrared and Raman spectra.

Copper(I) perchlorate, nitrate, and acetylacetonate complexes of the types Cu(triphos)ClO4 (triphos = CH3C(CH2PPh2)3), Cu(Cy3P)2ClO4 (Cy3P = P(C6H11)3), Cu(triphos)NO3, Cu(Cy3P)2(HFac)(HFac = hexafluoroacetylacetonate), and Cu (Cy3P)2(TtFac) (TtFac = thienyltrifluoroacetylacetonate) have been synthesized by reduction of the corresponding perchlorate, nitrate, and acetylacetonates with tertiary phosphines. Infrared spectra indicate the presence of monodentate perchlorate groups in Cu(triphos)ClO4 and in Cu(Cy3P)2ClO4 and the crystal structure of the latter has been determined by a three-dimensional X-ray analysis using diffractometer data. The crystals are monoclinic, space group C2/c, with cell dimensions a = 18.159(6), b = 9.493(2), c = 22.182(3) Å, and β = 95.41(2)° and four molecules per unit cell. The structure was refined by block-diagonal least squares methods to a final R of 0.051 for 2617 reflections using anisotropic thermal parameters for the nonhydrogen atoms. The structure consists of discrete Cu(Cy3P)2ClO4 molecules with symmetry C2 separated by normal van der Waals distances. The copper atom is three-coordinate and the perchlorate anion is monodentate but disordered over two sites. Principal dimensions include: Cu—P 2.262(1) Å, Cu—O 2.220(7) Å, [Formula: see text][Formula: see text] and 99.8(2)°, and [Formula: see text]

5-Methylthio-2-thioxo-1,3-dithiole-4-carboxamides (2a–e), the methyl 5-methylthio-2-thioxo-1,3-dithiole-4-carboxythiolate (9), and 3-alkyl-5-bis(alkylthio)methylene-2-thioxo-1,3-thiazole-4(5 H)-ones (4a–f) are obtained by reaction of the corresponding N-substituted ethylxanthogen-acetamides (1, 3, 6) with carbon disulfide under basic conditions followed by alkylation.5-Methylthio-2-thioxo-1,3-dithiole-4-carboxyl N-methyl-anilide (2d) was characterized by an X-ray crystal structure determination (space group P 1̄, a = 877.3(1), b = 1111.1(2), c = 837.6(1) pm, α = 104.22(2), β = 110.41(1), γ = 69.64(2)°, Ζ = 2, R = 0.039 for 1746 observed unique reflections).The α-oxoketene dithioacetal moiety of the molecule exhibits a noticeable derivation from planarity by a twist of the carbonyl group out of the ethylene plane and shows a short intramolecular S ··· O contact of 277.1 (3) pm.
