Abstract

Reaction of N-benzoyl-N′, N′-dimethylthiourea (HL) with copper (II) chloride yielded simultaneously two novel dimers: a pale green bis (µ-sulfur) bridged copper (II) dimer 1,[{CuL (HL) Cl} 2], and a dark green bis (µ-oxo) bridged copper (II) dimer 2,[{CuL2} 2], instead of the mononuclear copper (II) complexes,[CuL2], usually formed from other dialkyl- substituted benzoylthiourea ligands. The molecular structures of 1 and 2 have been ...
