The title compound, [CdBr2(C6H14N2O)], was synthesized upon complexation of 4-(2-aminoethyl)morpholine and cadmium(II) bromide tetrahydrate at 303 K. It crystallizes as a centrosymmetric dimer, with one cadmium atom, two bromine atoms and one N,N′-bidentate 4-(2-aminoethyl)morpholine ligand in the asymmetric unit. The metal atom is six-coordinated and has a distorted octahedral geometry. In the crystal, O...Cd interactions link the dimers into a polymeric double chain and intermolecular C—H...O hydrogen bonds form R 2 2(6) ring motifs. Further C—H...Br and N—H...Br hydrogen bonds link the components into a three-dimensional network. As the N—H...Br hydrogen bonds are shorter than the C—H...Br interactions, they have a larger effect on the packing. A Hirshfeld surface analysis reveals that the largest contributions to the packing are from H...H (46.1%) and Br...H/H...Br (38.9%) interactions with smaller contributions from the O...H/H...O (4.7%), Br...Cd/Cd...Br (4.4%), O...Cd/Cd...O (3.5%), Br...Br (1.1%), Cd...H/H...Cd (0.9%), Br...O/O...Br (0.3%) and O...N/N...O (0.1%) contacts.

A novel compound, 2-(morpholino)ethylammonium picrate monohydrate (MEAPM), was synthesized using the equimolar ratio of 4-(2- aminoethyl)morpholine and picric acid. . With the slow evaporation solution growth technique, single crystals of the synthesized compound were grown. A single crystal X-ray diffraction study revealed that MEAPM crystallizes in a triclinic system with space group P. The functional groups of the title compound were confirmed by FTIR analysis. A UV-Vis-NIR optical study indicated a cut-off wavelength of 370 nm. The UV-Vis-NIR spectrum was also used to calculate the optical parameters, such as the linear absorption coefficient, linear refractive index, and extinction coefficient. The two-photon coefficient absorption coefficient and third-order optical nonlinearity of the grown crystal were investigated using the Z-scan technique. The order susceptibility is found to be 2.96x10-11 esu. A dielectric study on MEAPM revealed a dielectric constant and dielectric loss at higher frequencies. The various hardness parameters were calculated via a Vickers hardness study. The work-handing coefficient is found to be 5.2. The thermal stability of the sample was investigated by TG-DTG analysis.

“…Morpholine can be used as a ligand in metal complexes and it can also be a component of protective coatings on fresh fruits and used as an emulsifier in the preparation of pharmaceuticals and cosmetic products (Kuchowicz & Rydzyn ´ski, 1998). As a continuation of our recent work on compounds belonging to the morpholine family (Chidambaranathan et al, 2023) we are now using morpholine as ligand for coordination complexes. The current study describes the synthesis, crystal structure, Hirshfeld surface, and infrared spectroscopy of bis[4-(2-aminoethyl)morpholine-2 N:N 0 ]diaquanickel(II) dichloride.…”

The title coordination compound, [Ni(C6H14N2O)2(H2O)2]Cl2, was synthesized by mixing 4-(2-aminoethyl)morpholine and nickel chloride in double-distilled water. The asymmetric unit comprises one half of an NiII cation (located on an inversion centre), one 4-(2-aminoethyl)morpholine ligand, one coordinated water molecule and one chloride ion outside the metal coordination sphere. The nickel ion is in a octahedral environment of the N4O2 type, coordinating four N atoms from two 4-(2-aminoethyl)morpholine ligands and two trans-located O atoms from two water molecules. The morpholine ligand was found disordered over two positions with a site occupancy ratio of 0.708 (8):0.292 (8). The crystal structure is consolidated by N—H...Cl, N—H...O, C—H...Cl and C—H...O hydrogen bonds. Hirshfeld surface analysis confirms that van der Waals interactions are prevalent in the crystal packing of the synthesized complex.
