Deskripsi
The title dinuclear complex, [Er2(C8H7O3)6(C10H8N2)2(H2O)2]·H2O, contains two ErIII atoms in the asymmetric unit, six 2-(4-hydroxyphenyl)acetate (PAA) anions, two 4,4′-bipyridine (bipy) molecules, two coordinated water molecules and one solvent water molecule. The central ErIII atoms are nine-coordinated. The coordination environment includes six O atoms from three PAA anions, one bridging O atom from a PAA anion, one O atom from a water molecule and an N atom from a bipy ligand in a distorted tricapped trigonal–prismatic geometry. The occurrence of numerous O—H...O and O—H...N hydrogen bonds involving coordinated and noncoordinated water as well as bipy groups builds up an intricate three-dimensional network.
