{?-6,6'-Dimeth-oxy-2,2'-[propane-1,3-diylbis(nitrilo-methyl-idyne)]diphenolato}trinitratocopper(II)erbium(III) acetone solvate.

ABSTRACT: In the title complex, [CuEr(C(19)H(20)N(2)O(4))(NO(3))(3)]·CH(3)COCH(3), the Cu(II) ion is coordinated in a square-planar environment by two O atoms and two N atoms of a Schiff base ligand. The Er(III) ion is bis-chelated by three nitrate ligands and coordinated by four O atoms of the Schiff base ligand in a slightly distorted bicapped square-anti-prismatic environment.

Aqua{6,6'-dimeth-oxy-2,2'-[propane-1,3-diylbis(nitrilo-methyl-idyne)]diphenolato}copper(II).

Project description:In the asymmetric unit of the title compound, [Cu(C(19)H(20)N(2)O(4))(H(2)O)], there are two independent mononuclear Cu(II) complexes. The coordination environment of each Cu(II) ion is square-pyramidal completed by two N atoms and two O atoms forming the basal plane, and one O atom of the water mol-ecule occupying the apical position. Neighbouring complexes are connected via O-H?O hydrogen bonds between the water mol-ecule and the meth-oxy group, forming a chain structure along the a axis. The propyl-ene groups of the two independent complexes are disordered over two positions with site occupancies of 0.361?(7):0.639?(7) and 0.224?(8):0.776?(8). The crystal under investigation was a partial inversion twin.

Project description:In the title heterodinuclear salen-type complex, [CuDy(C(19)H(20)N(2)O(4))(NO(3))(3)]·CH(3)OH, the copper(II) ion is tetra-coordinated by two imino N atoms [Cu-N = 1.961 (4) and 1.968 (4) Å] and two phenolate O atoms [Cu-O = 1.931 (3) and 1.938 (3) Å] in a planar geometry. The ten-coordin-ate Dy(III) ion is ligated by six O atoms of three nitrate groups and four O atoms from the ligand [Dy-O = 2.368 (3)-2.601 (3) Å]. In the crystal, complex mol-ecules and solvent mol-ecules are linked by inter-molecular O-H⋯O hydrogen bonds.

{6,6'-Dimeth-oxy-2,2'-[2,2-dimethyl-propane-1,3-diylbis(nitrilo-methyl-idyne)]diphenolato}nickel(II) 1.78-hydrate.

Project description:In the title complex, [Ni(C(21)H(24)N(2)O(4))]·1.78H(2)O, the Ni(II) ion has a slightly distorted planar geometry, coordinated by the two N and two O atoms of the tetra-dentate Schiff base ligand, with a mean deviation of 0.272?Å from the NiN(2)O(2) plane. The N and O donor atoms are mutually cis. The dihedral angle between two benzene rings of the ligand is 38.86?(8)°. There are also three solvent water mol-ecules, two of which lie across different crystallographic twofold rotation axes; one of these is partially occupied with a refined occupancy factor of 0.570?(7). The water mol-ecules are linked together as tetra-mers in R(2) (2)(8) ring motifs, which also connect two neighbouring mol-ecules of the complex through a network of O-H?O hydrogen bonds. The crystal structure is further stabilized by inter-molecular C-H?O and C-H?? inter-actions, which link neighbouring mol-ecules into extended chains along the b axis. Other inter-esting features of the crystal structure are the short inter-molecular C?C [3.204?(3)-3.365?(3)?Å] and the C?O [3.199?(2)-3.205?(2)?Å] contacts which are shorter than the sum of the van der Waals radii of these atoms.
