Sulfur-rich nickel(II) complex: Synthesis, characterization, and X-ray crystal structure

ABSTRACT

A sulfur-rich nickel complex has been synthesized by the reaction between 2,4-bis(4-methoxyphenyl)-1,3,2,4-dithiadiphosphetane-2,4-disulfide (Lawesson's reagent) and Ni(NO₃)₂·6H₂O in 2-propanol. The complex has been characterized by elemental analysis, IR, ¹H NMR, ¹³C NMR, and ³¹P NMR spectroscopies, and molar conductivity. Also, the crystal structure of the complex has been investigated by X-ray diffraction, which illustrates a slightly distorted square planar environment around Ni(II) ion in solid. Furthermore, the crystal structure of the complex shows 3D network through intermolecular C-H···Ni, C-H···O, and C-H···S hydrogen bonds and C–H···π interaction.
