Preparation and Characterization of the Adducts of Bis(N,N-diethyldithiocarbamato)oxovanadium(IV) and Copper(II) with n-Propylamine and Isopropylamine

Abstract

Two new 1:1 adducts of VO(dedtc) 2 , two 1:1 and two 1:2 adducts of Cu(dedtc) 2 (where dedtc = diethyldithiocarbamate) with n-propylamine and isopropylamine have been prepared. The resulting complexes have been characterized by elemental analysis, molar conductance, magnetic susceptibility, IR and UV-Vis spectral and TGA/DTA techniques. Analytical data reveals that VO(IV) complex forms only 1:1 adducts with the formula [VO(dedtc) 2 L] while Cu(II) complex forms both 1:1 and 1:2 adducts with 1:1 adducts having general formula Cu(dedtc) 2 . L and 1:2 adducts having general formula Cu(dedtc) 2 .L 2 (L = n-propylamine and isopropylamine). Antifungal activity of some complexes has been carried out against the fungal strain Sclerotium rolfsii. Electronic and magnetic measurements indicate a square pyramidal geometry for the 1:1 adducts of Cu(II) complex and an octahedral geometry for the 1:1 adducts of VO(IV) complex and for the 1:2 adducts of Cu(II) complex.

Mixed Ligand Complexes ofN-Methyl-N-phenyl Dithiocarbamate: Synthesis, Characterisation, Antifungal Activity, and Solvent Extraction Studies of the Ligand

“…A number of dithiocarbamate adducts have been reported in literature [ 4 , 12 – 18 ] with various geometries such as square planar [ 19 ], octahedral [ 20 , 21 ] and trigonal prismatic [ 22 ]. Interestingly, their pyridine [ 1 , 12 , 13 ], 2,2′-bipyridine [ 13 , 15 ] triphenylphosphine [ 10 ], and 1,10-phenanthroline [ 1 , 15 ] adducts have been reported to possess antifungal properties. Some show activities against broad spectrum and are more active compared to their parent metal complexes and uncomplexed ligand [ 10 ].…”

Dithiocarbamates: Challenges, Control, and Approaches to Excellent Yield, Characterization, and Their Biological Applications

“…Adducts are compounds with higher coordination numbers due to the addition of one or two Lewis bases molecules or polymerization of divalent metal dithiocarbamate complexes [33]. Lewis bases with bidentate N, N-donor bases, such as 2, 2′-bipyridine, 1, 10-phenanthroline, pyridine, methyl pyridine, and triphenylphosphine had been reported [37–45].…”

Synthesis and Characterization of Co (II), Ni (II), Cu (II), and Pd(II) Complexes with mono sodium 2,4,6-trioxotetrahydropyrimidine-1(2H)-carbodithioate

“…We noticed all complexes show a single peak at the range (991-1030) cm -1 [19,20] ,that is mean the ligand is bidentate through two sulfur atoms. The bands at (418-475) cm -1 could be attributed to υ (M-OH2) [21] .…”
