چکیده
The title complex, [Nd(2)(C(8)H(3)NO(6))(2)(C(8)H(4)NO(6))(2)(H(2)O)(6)]·2H(2)O, consists of dimeric units related by an inversion center. The Nd(III) atom is nine-coordinated by three O atoms from water mol-ecules and six from carboxyl-ate atoms. The 1,2-dicarboxylate acid molecules are in a single and double deprotonation stage and exhibit two coord-in-ation modes, viz. μ(2)-(κ(4), O(1): O(2): O(2): O(3)) and μ(1)-(κ(2), O(2): O(3)), which are responsible for the dimeric structure framework. The dimeric structure is then assembled into a three-dimensional supramolecular framework via O-H⋯O hydrogen bonds.

In the dimeric centrosymmetric title complex, [Er(2)(C(10)H(11)O(4))(6)(C(12)H(8)N(2))(2)], the Er(III) ion is nine-coordinated by five 2-(3,4-dimeth-oxy-lphen-yl)acetic acid (DMPA) ligands via seven O atoms and two N atoms from a bis-chelating 1,10-phenanthroline (phen) ligand in a distorted tricapped trigonal-prismatic geometry. The DMPA ligands are coordinated to the Er(III) ion in bis-chela...

In the centrosymmetric dinuclear complex anion of the title compound, (C(5)H(8)N(3))(2)[Bi(2)(C(7)H(3)NO(4))(4)(H(2)O)(2)]·4H(2)O, the Bi(III) atom is eight-coordinated in an N(2)O(6) environment and has a distorted bicapped trigonal-prismatic coordination environment. Extensive inter-molecular O-H⋯O, N-H⋯O and weak C-H⋯O hydrogen bonds lead to the stability of the crystal structure. Inter-acti...
