Castro, Rodrigo A.; Oliveira, Marcelo R. L.; Janczak, Jan; Rubinger, Mayura M. M.The potassium N-R-sulfonyldithiocarbimates, K2(RSO2NCS2) [R = CH3 (1a), CH3CH2 (1b), C6H5 (1c), 2-CH3C6H4 (1d) and 4-CH3C6H4 (1e)], reacted with nickel sulfate or zinc acetate to yield complex anions which were isolated as their tetraphenylphosphonium salts with the formulae (PPh4)2[M(RSO2NCS2)2], were M = Ni (2a–2e) and M = Zn (3a–3e). The compounds 3a–3e readily react with sulfur in dimethylformamide producin...

Oliveira, Marcelo R. L.; Perpetuo, Genivaldo J.; Janczak, Jan; Rubinger, Mayura M. M.Two new zinc(II)-complexes, dithiocarbimato (Ph4P)2[Zn(CH3SO2N=CS2)2] (1) and trithiocarbimato (Ph4P)2[Zn(CH3SO2N=CS3)2] (2), were obtained in the crystalline form by the reaction of potassium N-methylsulfonyldithiocarbimate (RSO2N=CS2K2) with zinc(II) acetate dihydrate and tetraphenylphosphonium chloride in dimethylformamide. Both complexes crystallize in the monoclinic system. The central Zn(II) ion has a dis...

Perpétuo, Genivaldo Julio; Janczak, JanTwo single crystals of 1-(diaminomethylene) thiouron-1-ium benzoate (1) and bis(1-(diaminomethylene) thiouron-1-ium) phthalate trihydrate (2) were grown using a solution growth technique. The compound 1 crystallises in the centrosymmetric P21/c space group of the monoclinic system, whereas the compound 2 in the centrosymmetric Pbcn space group of orthorhombic system. The solid-state organisation of 1 and 2 has ...

Perpétuo, Genivaldo Julio; Gonçalves, Rafael Silva; Janczak, JanThe single crystals of 1-(diaminomethylene)thiouron-1-ium 4-hydroxybenzenesulfonate were grown using a solution growth technique. The compound crystallises in the centrosymmetric P21/c space group of the monoclinic system. The conformation of the 1-(diaminomethylene)thiouron-1-ium cation is not strictly planar, but twisted. Both arms of the cation are oppositely rotated by 8.5(1)_ around the CAN bonds involving...
