Two sulfonated resorcinarenes were synthesized by reacting C-tetra(butyl) resorcinarene or C-tetra(2-(methylthio)ethyl)resorcinarene with formaldehyde in the presence of sodium sulfite. Their structures were determined via FT-IR, 1H-NMR, 13C-NMR and mass spectrometry. Thermal gravimetric analyses of the derivatives were also carried out and revealed the presence of water molecules in the solid ...

Tetra-kis(2-methyl-prop-yl)thio-per-oxy-dicarbonic di-amide, or tetra-iso-butyl-thiuram di-sulfide, C18H36N2S4, crystallizes in a general position in the triclinic space group P-1 but shows pseudo-C2 symmetry about the di-sulfide bond. The C-S-S-C torsion angle [-85.81 (2)°] and the dihedral angle between the two NCS2 mean planes [85.91 (5)°] are within the range observed for this compound type...

The title compound, C33H35N3O5, is the product of the multicomponent condensation of 1-benzyl-4-eth-oxy-carbonyl-piperidin-3-one with 1,5-bis-(2-formyl-phen-oxy)-3-oxapentane and ammonium acetate. The mol-ecule comprises a penta-cyclic system containing the aza-14-crown-4-ether macrocycle, tetra-hydro-pyrimidine, tetra-hydro-pyridine and two benzene rings. The aza-14-crown-4-ether ring adopts a...

A cyclometalated bisruthenium complex bridged by the 2,7-bisdeprotonated form of 1,3,6,8-tetra(pyridin-2-yl)-9-butyl-9H-carbazole displays appreciably enhanced electronic coupling relative to that with the 5,5'-bisdeprotonated form of 3,3',5,5'-tetra(pyridin-2-yl)-biphenyl as the bridge.

The title compound, [Ni(C(5)H(9)N)(3)(CO)], was prepared from Ni(CO)(4) and a tenfold excess of tert-butyl isocyanide. It crystallizes with two symmetry-independent mol-ecules per asymmetric unit. The central Ni atom of each independent mol-ecule has a nearly perfect tetra-hedral coordination environment, comprising one carbon monoxide and three isocyanide ligands. The title compound is the fir...
