Pursuing new facts in the coordination capabilities of (1-diaminomethylene)thiourea (HATU): Products of the interaction with transition metal halides – Structural investigations

This work is part of our studies on the reactivity and crystal engineering of (1-diaminomethylene)thiourea (HATU). Structure and other properties of the selected products of the interaction of HATU with transition metal halides, also in the presence of 3% hydrogen peroxide as an oxidizing agent, have been investigated ((1) di-μ-((1-diaminomethylene)thiouron-1-ium)-κ4S:S-bis[chlorido((1-diaminomethylene)-thiouron-1-ium-κS)copper(I)] tetrachloride [(C2H7N4S)4CuI2Cl2]Cl4, (2) catena(bis(3,5-diamino-1,2,4-thiadiazol-2-ium)-bis(μ2-chlorido)-chloridocuprate(II)) [(C2H6N4S)2(Cu2Cl6)]∞, (3) 3,5-diamino-1,2,4-thiadiazol-2-ium pentachloridoferrate(III) (C2H6N4S)2[FeCl5], (4) 3,5-diamino-1,2,4-thiadiazol-2-ium chloride) (C2H6N4S)Cl, (5) 3,5-diamino-1,2,4-thiadiazol-2-ium tetrachloridozincate(II) (C2H7N4S)2[ZnCl4]. For (2) also magnetic properties have been characterized. Compound (3) contains unusual pentachloridoferrate(III) anions.

Structure and other properties of the selected products of the interaction of (1-diaminomethylene)thiourea (HATU) with transition metal halides, also in the presence of 3% hydrogen peroxide as an oxidizing agent, are presented.Figure optionsDownload as PowerPoint slide
