“…The single crystal structural analysis revealed that the complexation products of L n with CuX (X = Cl, Br, I) turned out to be the discrete supramolecular Cu I complexes, instead of an infinite coordination polymer. Reactions of L 1 (1) with CuX gave the dinuclear metallamacrocyclic complexes (L 1 CuX) 2 [X = Cl (4), Br (5), I (6)], whereas the complexation of L 2 (2) or L 3 (3) with CuBr produced the tetranuclear copper clusters [L n (CuBr) 2 ] 2 [n = 2 (7), 3 (8)]. Interestingly, L 3 (3) supported the formation of trinuclear complexes (L 2 CuX) 3 [X = Cl (9) I (10)] with a threeblade propeller structure.…”

The reported results show that the mono-acylthiourea H 2 L ligands are less competent in self-assembly with Cu I halide in a 2:1 stoichiometry, in a monomeric or dimeric configuration or in a 3:1 composition, respectively to give mononuclear or dinuclear complexes.…”

“…Due to the low quality of single crystals, the molecular structure of 7 could not been solved with a high level of accuracy. [28] However, the data obtained allowed unambiguously to determine the structure as the discrete tetranuclear complex [L 2 (CuBr Similarly, the 1:2 reaction of L 3 (3) with CuBr led to the production of [L 3 (CuBr) 2 ] 2 (8) (see Scheme 4) in moderate yield (60 %). The single-crystal X-ray diffraction analysis revealed that 8 ( Figure 2) is isostructural to 7 in view of the tetranuclear composition and the resulting S 4 Cu 4 Br 4 core.…”

“…Acylthiourea derivatives containing the C(O)NHC(S)N core fragment have been well recognized due to their biological, [1] optical, [2] analytical, [3] and catalytic properties. [4] Their Cu I complexes are also attractive in view of the metal-based drugs.…”

Three diacylthioureas 1,4‐C6H4[C(O)NHC(S)NHAr]2 (Ar = 2,6‐iPr2C6H3) (L1, 1), 1,3‐C6H4[C(O)NHC(S)NHAr]2 (L2, 2), and 1,3‐C6H4[C(O)NHC(S)NHAr′]2 (Ar′ = 2,6‐Me2C6H3) (L3, 3) were synthesized and characterized. The CuI complexes from the reactions of bipodal ligands Ln with CuX (X = Cl, Br, I) were structurally investigated by single‐crystal X‐ray diffraction methods. Treatment of L1 with CuX gave the metallamacrocyclic complexes (L1CuX)2 [X = Cl (4), Br (5), I (6)] with the ligand to metal in a ratio of 2:2, where both sulfur and halide anions function as terminal substituents. In contrast, when L2 or L3 was reacted with CuBr, the two Ln ligands coordinate to four copper atoms each in a bridging and terminal fashion to yield [Ln(CuBr)2]2 [n = 2 (7), 3 (8)]. The obtained S4Cu4Br4 core contains all four bromide anions in bridging positions. The reaction of L3 with CuX (X = Cl, I) gave the 3:3 trinuclear complexes (L3CuX)3 [X = Cl (9) I (10)], interconnected by halide bridges. The obtained diacylthioureas (1–3) and their CuI complexes (4–10) were also characterized by elemental analysis, FT‐IR, 1H and 13C NMR spectroscopy.

The reaction of [(p‐cymene)RuCl2]2 and [Cp*MCl2]2 (M = Rh/Ir) with benzoyl (2‐pyrimidyl) thiourea (L1) and benzoyl (4‐picolyl) thiourea (L2) led to the formation of cationic complexes bearing formula [(arene) M (L1)к2(N,S)Cl]+ and [(arene) M (L2)к2(N,S)Cl]+ [(arene) = p‐cymene, M = Ru, (1, 4); Cp*, M = Rh (2, 5) and Ir (3, 6)]. Precursor compounds reacted with benzoyl (6‐picolyl) thiourea (L3) affording neutral complexes having formula [(arene) M (L3)к1(S)Cl2] [arene = p‐cymene, M = Ru, (7); Cp*, M = Rh (8), Ir (9)]. X‐ray studies revealed that the methyl substituent attached to the pyridine ring in ligands L2 and L3 affects its coordination mode. When methyl group is at the para position of the pyridine ring (L2), the ligand coordinated metal in a bidentate chelating N, S‐ mode whereas methyl group at ortho position (L3), it coordinated in a monodentate mode. Further the anti‐cancer studies of the thiourea derivatives and its complexes carried out against HCT‐116, HT‐29 (human colorectal cancer), Mia‐PaCa‐2 (human pancreatic cancer) and ARPE‐19 (non‐cancer retinal epithelium) cell lines showed that the thiourea ligands are inactive but upon complexation, the metal compounds displayed potent and selective activity against cancer cells in vitro. Iridium complexes were found to be more potent as compared to ruthenium and rhodium complexes.

A novel mixed platinum(II) complex with general formula [Pt(PPh 3 ) 2 (L 1 -O,S)]PF 6 has been synthetized and characterized by elemental analysis, molar conductivity, and by IR and NMR ( 1 H, 13 C and 31 P) spectroscopic methods. The crystal structure has been determined by single-crystal X-ray crystallography. The molecule presents an almost ideal square-planar geometry, and the crystal is stabilized by weak C-H···O and C-H···F hydrogen bonds, and C-H···π stacking interactions. The steric congestion of ligands is described by "exact" cone and [a]
