“…This structural diversity originates from the propensity of the halide to act as terminal or bridging ligand and of the thiourea ligand to coordinate in a monodentate or a bridging mode 36. In the known tetranuclear Cu I systems with sulfur donor, the adamantanoid cages often contain the Cu 4 S 6 core,38 in which simply the soft anions like halides have the chance to bind with the copper site in a terminal fashion (Cl,39 I13,37). Only one comparable example involving edge‐bridging bromine atoms in the P 4 Cu 4 Br 4 core with adamantane‐like topology was established by treatment of 1, 1′‐diphosphaferrocene with CuBr, but with single conformation 36.…”

Abstract. The N-(2,6-diisopropylphenyl)-NЈ-benzoylthiourea ligand (shown as L) (1) was synthesized and characterized. Reactions of 1 with CuCl 2 and CuBr 2 afforded the monomeric L 2 CuCl (2) and dimeric [LBrCu(μ-L)] 2 (3), respectively, due to the reduction of Cu II . The reaction of 1 and CuCl gave the same product L 2 CuCl (2), while the treatment of 1 with CuBr led to the formation of a rare example

“…A considerable number of complexes of simple copper(I) salts, formed with thiourea and its derivatives, relevant in many biological and pharmaceutical areas, , and involving a wide variety of compositions and structures, have been reported in the past; − in these, thiourea behaves as a “soft” ligand, capable of unidentate or diverse bridging modes in its complexes with copper(I) salts, associated “hard” anions usually being excluded from the coordination sphere while “soft” anions such as the heavier halide ions (i.e., not F) may be competitive. In the context of crystallization from diverse solvents, the strong hydrogen-bonding characteristics, capable of modification by substitution, may be relevant.…”

Crystal Structures and Vibrational Spectroscopy of Copper(I) Thiourea Complexes

Several synthetic strategies using copper(I) starting materials or copper(II) compounds and an in situ sulfite reductant have been used to systematically explore the chemistry of copper(I) complexes with thiourea and substituted thiourea ligands. This has resulted in the discovery of several new complexes and methods for the bulk synthesis of some previously reported complexes that had been prepared adventitiously in small quantity. The new complexes are (tu = thiourea, dmtu = N,N'-dimethylthiourea, etu = ethylenethiourea): [I(4)Cu(4)(tu)(6)].H(2)O, [Cu(4)(tu)(10)](NO(3)).tu.3H(2)O, [BrCu(dmtu)(3)], [ICu(dmtu)(3)](2), [BrCu(etu)(2)](2), [ICu(etu)(2)], [ICu(etu)(2)](3). [I(4)Cu(4)(tu)(6)].H(2)O has an adamantanoid structure, with four terminal iodide ligands and six doubly bridging tu ligands. In contrast to this, [Cu(4)(tu)(10)](NO(3)).tu.3H(2)O contains a tetranuclear cluster in which four of the tu ligands are terminal and the other six are doubly bridging. [BrCu(dmtu)(3)] is a mononuclear complex with tetrahedral coordination of copper by one bromide and three dmtu ligands, whereas [Cu(dmtu)(3)](2)I(2) has a centrosymmetric dimeric cation with two uncoordinated iodides, four terminal dmtu and two doubly bridging dmtu ligands, [(dmtu)(2)Cu(mu-S-dmtu)(2)Cu(dmtu)(2)]I(2). A reversal of this monomer to dimer trend from bromide to iodide is seen for the etu counterparts: [BrCu(etu)(2)](2) is a centrosymmetric dimer with two doubly bridging etu ligands, [(etu)BrCu(mu-S-etu)(2)CuBr(etu)], whereas [ICu(etu)(2)] is a trigonal planar monomer, although the novel [I(3)Cu(3)(etu)(6)] is also defined. Infrared and Raman spectra of the synthesized complexes were recorded and the metal-ligand vibrational frequencies have been assigned in many cases. The results confirm previously observed correlations between the vibrational frequencies and the corresponding bond lengths for complexes of the unsubstituted tu ligand. A mechanochemical/infrared method was used to synthesize [I(3)Cu(3)(etu)(6)] from CuI and etu, and to demonstrate the polymorphic transition from [ICu(etu)(2)] to [I(3)Cu(3)(etu)(6)].

N‐Аlkenyl thioureas, under the action of aryltellurium trichlorides, form the addition products N‐{2‐chloro‐3‐[dichloro(4‐alkoxyphenyl)‐tellanyl]propyl} thioureas or the intramolecular cyclization products 5‐{dichloro(4‐alkoxyphenyl)‐telluromethyl}‐2‐phenylamino‐4,5‐dihydro‐1,3‐thiazole hydrochlorides. The reaction route depends on the nature of the substituent in the thiourea. The Fukui function reactivity indexes identify the electrophilic/nucleophilic centers and explain the possible cyclization reaction in the case of phenyl substituted thioureas. In the case of other substituents, the calculated values of partial atomic charges clearly predict that the addition reaction is more possible.
