Synthesis and Structure of the Cadmium (II) Complex: [Cd(C5H5N)2(S2CO-n-C4H9)2]

Abstract

The [Cd(C5H5N)2(S2CO-n-C4H9)2] adduct of pyridine with [Cd(S2CO-n-C4H9)2]n was synthesized and characterized by IR, elemental analysis, 1H-NMR and X-ray diffraction analysis. The crystasl belong to the monoclinic system, space group P2(1)/c with Z=2. Cell dimensions are a=1.1094(12), b=0.6152(6), c=1.7985(19) nm, • =96.148(2)°, V=1.2204(2)nm3. The tructure was refined to R=0.0246 and wR=0.0645 for 2624 reflections with I>2•(I). The complex has a centrosymmetric molecule structure.

Crystal Structure of Bis(<i>O</i>-Propyldithiocarbonato-<i>κ</i>²<i>S</i>,<i>S</i>′)(2,2′-bipyridine-<i>κ</i>²<i>N</i>,<i>N</i>′)nickel(II)

“…These values show a double-bond character due to delocalization over the two C-S bonds. 9 The bond angles in the pyridine ring vary from 118.1(3) to 122.6(6)˚, the average value being 119.9(3)˚. The dihedral angle between the dithio-group and the pyridine ring is 86.21(1)˚, which shows that the pyridine ring is held almost perpendicular to the dithiocarbonato group.…”

Synthesis, Characterization, and X-Ray Structure of Bis(O-butyldithiocarbonato)bis(3-ethyl pyridine)nickel(II)

“…The C-S bond lengths involving the xanthate ligands are S1-C1 = 1.684(4) and S2-C1 = 1.677(5)Å. These values show double bond character due to the delocalization over the two C-S bonds [19]. The bond angles in the pyridine ring vary from 117.8(4) to 124.1 (4) ∘ , the average value being 119.9(8) ∘ , and these values of bond angles and bond distances are in good agreement with those reported for some analogous Ni-dithiocarbonato complexes [20][21][22][23].…”

Synthesis, Structure and Characterization of Adducts of O-Propyldithiocarbonates with Substituted Pyridines

“…These values are same and they show double bond character that is due to the delocalization over the two C-S bonds 23 . The plane formed by two sulfur, a nickel and a carbon atoms (Ni1, S2, C7, S3) is planer and the dihedral angle between this plane and the plane of cyanopyridine ring is 89.25(4)° meaning thereby both these planes are held almost perpendicular to each other.…”
