Synthesis, crystal structure and Hirshfeld surface analysis of diacetatobis[4-(2-aminoethyl)morpholine]cadmium tetrahydrate

B. Chidambaranathan, S. Sivaraj, P. Vijayamathubalan and S. Selvakumar

In the title coordination compound, the Cd atom is octahedrally coordinated by two N,N′-bidentate ligands [4-(2-aminoethyl)morpholine] and two trans-located acetate molecules. The Cd atom is located on a centre of inversion, whereas the morpholine and four water molecules are adjacent to the acetate moieties. In the crystal, neighboring metal complexes and uncoordinated water molecules are linked via N—H

O and O—H

O hydrogen-bonding interactions.

Keywords: crystal structure; coordination compound; morpholine ligand; crystal structure.

Special details top

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.

Refinement. Acetate moiety is disordered over two positions with an occupancy ratio of 1:1. SADI restraint was used to fix similar distances to be equal for the disordered atoms. The anisotropic displacement parameters of atoms in the disordered groups were restrained to be equal with an effective standard deviation of 0.02A2 using SIMU restraint. Hydrogen, H6, on O5 water molecules is having two possible locations labelled as H6 and H6'. The refined occupancy ratio of H6 and H6' was found to be 47:53
