Synthesis, Crystal Structure, Hirshfeld Surface Analysis of Bis(N,N-Diethylenediamine)cadmium(II)] Dichloride

Abstract

A new Cd(II) complex, bis[(N,N-diethylenediamine)cadmium(II)] dichloride, C12H32CdCl2N4, was synthesized by the reaction between cadmium(II) chloride hexahydrate, sodium hydroxide, and N,N-diethylenediamine in aqueous methanol. The crystal structure was characterized by single-crystal X-ray diffraction analysis technique. The crystal structure is monoclinic, space group P2(1)/c with parameters a = 6.8959(3) angstrom, b = 16.0795(10) angstrom, c = 16.4406(8) angstrom, beta = 100.23(4)degrees, V = 1794(16) angstrom(3), Z = 4. The X-ray structure analysis reveals that the Cd(II) cation coordinated by four N atoms of the N,N-diethylenediamine units and two Cl atoms, giving it a octahedral geometry. In the crystal, the molecules are linked by N-HMIDLINE HORIZONTAL ELLIPSISCl hydrogen bond, forming a three-dimensional supramolecular architecture. A Hirshfeld surface analysis was performed to record various intermolecular interactions, indicating the stabilization of the Cd(II) complex structure by the intermolecular weak N-HMIDLINE HORIZONTAL ELLIPSISCl hydrogen bonds. The major interactions are HMIDLINE HORIZONTAL ELLIPSISH (80.2%) and ClMIDLINE HORIZONTAL ELLIPSISH (19.8%) interactions for the title complex.
