“…The slightly higher values than those expected for non-electrolytes in these cases are probably due to partial replacement of the anion by the strong donor solvent molecule and the two species may exist in equilibrium. Further, dissociation of coordinated halides in DMF leading to substantially high conductance has been reported in literature [23,24]. Therefore, the complexes may perhaps be considered as non-electrolytes.…”

The new mononuclear neutral metal complexes of the type [M(L) 2 (H 2 O) n X n ] (where n= 0,1,2…; X= Cl; ½ SO 4 ; CH 3 COO; Br) by using the metal(II/III) salts {M = Cu(II), Co(II), Ni(II), Pd(II) and Ru(III)} with the Clomiphene citrate (L) were synthesized. The ligand and its complexes were characterized by elemental analysis, infrared, ESR, 1 H-NMR, electronic spectral studies and magnetic susceptibility measurement, which reveals that L acts as a monodentate ligand. They simultaneously give Thermogravimetric and Differential Thermal Analysis patterns of the complexes recorded at heating rate of 10 °C min -1. The antimicrobial activity of ligand and its metal complexes were evaluated against Gram positive and Gram negative bacteria.

“…The complexes of Fe(III) (1) and Ru(III) (2) are low spin with (t 2g ) 5 configuration and showed a high intensity band around 420 nm, which is tentatively assigned to MLCT charge transfer [36,37], while the band at ca. 512 nm is attributed to ligand(p) ?…”

Complexes of a diacetylmonoxime Schiff base of S-methyldithiocarbazate (H2damsm) with Fe(III), Ru(III)/Ru(II), and V(IV); catalytic activity and X-ray crystal structure of [Fe(Hdamsm)2]NO3·H2O

The complexes [M(Hdamsm) 2 ]XÁH 2 O (M = Fe, X = NO 3 ; M = Ru, X = Cl), [Ru(Hdamsm)(PPh 3 ) 2 X 0 ] (X 0 = Cl, Br), and [VO(Hdamsm)(acac)] (H 2 damsm = diacetylmonoxime Schiff base of S-methyldithiocarbazate, Hacac = acetylacetone) have been prepared and characterized by spectroscopic techniques. Their redox properties were investigated by cyclic voltammetry. The X-ray crystal structure of [Fe(Hdamsm) 2 ]NO 3 .H 2 O has been determined and shows that the complex has a distorted octahedral geometry in which the Hdamsm behaves as a monoanionic NNS tridentate ligand coordinating via oxime nitrogen, hydrazinic imine nitrogen, and thiolate sulfur. The reactivity of these complexes toward oxidation of alcohols in the presence of t-BuOOH and H 2 O 2 as co-oxidants is reported.

“…Also, the IR spectrum of cis-Mo 2 O 5 (ahp) 2 shows a broad band at 700 cm À1 assigned to v(Mo 2 O) of the bridging oxo ligand [13,15]. The trans-UO 2 (ahp) 2 complex has a strong IR band at 902 cm À1 not observable in the Raman spectrum assigned to v asym (UO 2 ) of the trans-O U O moiety [13,16], whereas the strong Raman band at 890 cm À1 is assigned to v sym (UO 2 ) [13]. The complex ReO(PPh 3 )(ahp) 2 )I shows a new strong band at 967 cm À1 (IR) and 983 cm À1 (Raman) which arises from the v(ReO) stretch [17].…”

The new complexes cis-Mo 2 O 5 (ahp) 2 , trans-UO 2 (ahp) 2 , ReO(PPh 3 )(ahp) 2 I, M(ahp) 2 , and M H (ahp) 3 (M Co, Cu, Pd; M H Fe, Ru, Rh; ahp 2-amino-3-hydroxypyridine) have been prepared. The ligand binds via the deprotonated hydroxy oxygen atom and the amino nitrogen atom to the central ion. Infrared, Raman, 1 H NMR, and electronic spectra of the complexes have been recorded. 2-Amino-3-hydroxy pyridine was found to behave as an inhibitor with respect to the corrosion of aluminum and copper in acidic solutions.
