TL;DR: In this article, a comparison of the I.r. spectra of the 2-aminobenzothiazole (HL) complexes with those of the ligand, its deuterated DL and HL · HBr derivatives was made.
17 citations
TL;DR: In this paper, the following zinc (II), cadmium (II) and mercury (II)-complexes of 2-methyl-benzoxazole (L) have been prepared and studied by conductometric and i.r. methods.

TL;DR: In this article, the following ethylenediamine(sulphamide)nickel(II) complexes were prepared: Ni(en)3(H2Su)Cl2, in which H2Su is not coordinated; Ni(n)2(Hsu)Cl 2, Ni(m)2HSuCl 2 · EtOH, Ni(e.r.t.
Abstract: The following ethylenediamine(sulphamide)nickel(II) and ethylenediamine(sulphamide)copper(II) complexes were prepared: Ni(en)3(H2Su)Cl2, in which H2Su is not coordinated; Ni(en)2(H2Su)Cl2 , Ni(en)2(HSu)Cl · EtOH, Ni(en)2(HSu)2,Ni(en)2(HSu)2(H2Su)2 · EtOH, Cu(en)2(HSu)2(H2Su) · O.5EtOH, in which the sulphamide molecule, H2Su, or the sulphamidato anion [HSu] are totally or partially coordinated. The comparison of the i.r. spectra of these complexes with those of H2 Su and NaHSu and with those of the M(en)2Cl2 complexes permits the isolation of the sulphamide or sulphamidato ν(SO2) and ν(SN2) bands which show oxygen-coordination of these ligands to the metal. Some ν(MO) bands were identified in the far i.r. region.

TL;DR: The following copper and silver complexes of 2-aminobenzothiazole (L) were prepared and studied by conductometric and i.r. methods: MX · 0.5L (M = Cu, X = I; M = Ag and X = Cl, I), MX · L (M, X, Cl, Br; M, Ag and Br; X = Br), CuClO 4 · 1.5l, AgX · 2L (X = NO 3, ClO 4, BF 4, CF 3 COO) as discussed by the authors.
4 citations

TL;DR: In this article, the Schiff base was shown to act as bidentate ligand through the pyridine-like imine nitrogen of imidazole ring and the azomethine nitrogen.
Abstract: The reactions of divalent nickel and copper salts with the Schiff base derived from 2-(2-aminophenyl)benzimidazole and benzaldehyde, L, yield complexes of general formulae [CuL2X2] (X=Cl, Br, or ClO4), [CuL(SO4)], [CuL(SO4)] · 4H2O, and NiLX2 (X=Cl, Br, or NCS). All the complexes have been characterized by elemental analyses, magnetic measurements, e.s.r. electronic and i.r. spectral studies. The results show that the Schiff base acts as bidentate ligand through the pyridine-like imine nitrogen of imidazole ring and the azomethine nitrogen. Tentative structures of the complexes are suggested.
