[Cd(OPD)3SO4]•H2O Synthesis, structure and Hirshfeld surface analysis of the complex compound based on Cd(II) salt and O-phenylenediamine

Abstract

In this paper studying the synthesis, crystal structure and Hirschfeld surface analysis of a new complex compound containing [Cd(OPD)₃SO₄]·H₂O obtained based on o-phenylenediamine (OPD) are given. The molecular and crystal structure of this complex compound was determined using the RTT method. In the inner sphere of the complex, two molecules of OPD in the chelate state and one molecule of OPD in the monodentate state are attached to the central atom. The complex compound forms a distorted octahedral shape in space. [Cd(OPD)₃SO₄]·H₂O complex compound syngonia is monoclinic, space group P21/c and crystal parameters are a = 22.5631(5)Å, b = 8.1292(2) Å, c = 11.6094(4) Å. In the crystal structure of the complex, 5 Cd−N (2.350(5) Å − 2.448(5) Å) and 1 Cd−O (2.355(5) Å) bonds form an inner sphere. The crystal structure of the molecule is formed by intra- and intermolecular hydrogen bonds of the type N---H...O and O---C...O. In the Hirschfeld surface analysis of [Cd(OPD)₃SO₄]·H₂O complex compound, the main interactions are H...H (54.4%), O...H/H...O (26.7%) and H...C/C...H (16.7%) organizes.
