RESUMO
The title compound, [CdBr2(C6H14N2O)], was synthesized upon complexation of 4-(2-aminoethyl)morpholine and cadmium(II) bromide tetra-hydrate at 303â 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 octa-hedral geometry. In the crystal, Oâ¯Cd inter-actions link the dimers into a polymeric double chain and inter-molecular C-Hâ¯O hydrogen bonds form R 2 2(6) ring motifs. Further C-Hâ¯Br and N-Hâ¯Br hydrogen bonds link the components into a three-dimensional network. As the N-Hâ¯Br hydrogen bonds are shorter than the C-Hâ¯Br inter-actions, they have a larger effect on the packing. A Hirshfeld surface analysis reveals that the largest contributions to the packing are from Hâ¯H (46.1%) and Brâ¯H/Hâ¯Br (38.9%) inter-actions with smaller contributions from the Oâ¯H/Hâ¯O (4.7%), Brâ¯Cd/Cdâ¯Br (4.4%), Oâ¯Cd/Cdâ¯O (3.5%), Brâ¯Br (1.1%), Cdâ¯H/Hâ¯Cd (0.9%), Brâ¯O/Oâ¯Br (0.3%) and Oâ¯N/Nâ¯O (0.1%) contacts.
RESUMO
The title coordination compound, [Cd(C2H3O2)2(C6H14N2O)2]·4H2O, was synthesized by mixing 2 moles of 4-(2-amino-eth-yl)morpholine and 1 mole of cadmium acetate in double-distilled water. The Cd atom is octa-hedrally coord-inated by two N,N'-bidentate ligands [4-(2-amino-eth-yl)morpholine] and two trans-located acetate mol-ecules. The Cd atom is located on a center of inversion, whereas the 4-(2-amino-eth-yl)morpholine and four water mol-ecules are adjacent to the acetate mol-ecules. The chair conformation of the morpholine mol-ecules is confirmed. In the crystal, adjacent metal complexes and uncoord-inated water mol-ecules are linked via N-Hâ¯O and O-Hâ¯O hydrogen-bonding inter-actions, generating R 2 2(6), R 6 6(16), R 6 6(20) and S 1 1(6) motifs and forming a three-dimensional network. A Hirshfeld surface analysis indicated the contributions of various contacts: Hâ¯H (71.8%), Oâ¯H/Hâ¯O (27.1%), and Câ¯H/Hâ¯C (1.0%).
