Tetra­kis[μ-2-(3,4-dimeth­oxy­phen­yl)acetato]-κ3 O 1,O 1′:O 1;κ3 O 1:O 1,O 1′;κ4 O 1:O 1′-bis­{[2-(3,4-dimeth­oxy­phen­yl)acetato-κ2 O 1,O 1′](1,10-phenanthroline-κ2 N,N′)erbium(III)}

In the dimeric centrosymmetric title complex, [Er2(C10H11O4)6(C12H8N2)2], the ErIII ion is nine-coordinated by five 2-(3,4-dimeth­oxy­lphen­yl)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 ErIII ion in bis-chelate, bridging and bridging tridentate modes. Relatively weak intra­molecular C—H⋯O inter­actions reinforce the stability of the mol­ecular structure. Inter­molecular C—H⋯O inter­actions are also observed

Tris{2-meth­oxy-6-[(4-methyl­phen­yl)iminiometh­yl]phenolate-κ2 O,O′}tris­(thio­cyanato-κN)europium(III)

The metal center in the structure of the title compound, [Eu(NCS)3(C15H15NO2)3], is coordinated by three Schiff base 2-meth­oxy-6-[(4-methyl­phen­yl)iminiometh­yl]phenolate (L) ligands and three independent thio­cyanate ions. In the crystal structure, the acidic H atom is located on the Schiff base N atom and hydrogen bonded to the phenolate O atom. The coordination environment of the EuIII ion is nine-coordinate by three chelating methoxy­phenolate pairs of O atoms and three N-atom terminals of the thio­cyanate ions. The compound is isostructural with the CeIII analogue [Liu et al. (2009 ▶). Acta Cryst. E65, m650]

In the centrosymmetric dinuclear title complex, [Sm2(C10H11O4)6(C12H8N2)2], the SmIII ion is nine-coordinated by seven O atoms of five 2-(3,4-dimeth­oxy­phen­yl)acetate (DMPA) ligands and two N atoms of one bis-chelating 1,10-phenanthroline (phen) ligand, forming a distorted tricapped trigonal-prismatic environment. The DMPA ligands coordinate in bis-chelate, bridging and bridging tridentate modes. An intra­molecular C—H⋯O hydrogen bond occurs. Inter­molecular C—H⋯O inter­actions are also present in the crystal

Tris{2-meth­oxy-6-[(4-methyl­phen­yl)iminiometh­yl]phenolato-κ2 O,O′}tris­(thio­cyanato-κN)praseodymium(III) monohydrate

The asymmetric unit of title compound, [Pr(NCS)3(C15H15NO2)3]·H2O, consists of three Schiff base 2-meth­oxy-6-[(4-methyl­phen­yl)imino­meth­yl]phenol (HL) ligands, three independent thio­cyanate anions and an uncoordinated water mol­ecule. The PrIII ion is nine-coordinated. The thio­cyanate anions coordinate to the PrIII ion via the N atoms and the three HL ligands chelate the PrIII ion via the phenoxy and meth­oxy O atoms. The protonated imine N atoms are involved in intra­molecular hydrogen bonds with the phenolate groups
