چکیده
The title compound, [Eu(III)(NO(3))(2)(C(24)H(28)Cl(2)N(6)O(2))]NO(3)·0.5CH(3)OH, is isostructural with the Gd(III) and Ho(III) complexes of the analogous macrocyclic ligand, with both Cl atoms replaced by methyl groups. The Eu atom exhibits a nine-coordinate distorted tricapped trigonal-prismatic coordination geometry. The methanol solvent mol-ecule is disordered about a twofold rotation axis with occupancies of 0.543 (12):0.457 (12).

The title co-crystal, [Eu(NCS)3(C18H15OP)3][Eu(NCS)2(NO3)(C18H15OP)3], contains two distinct neutral complexes. Each complex has threefold symmetry about its central Eu(3+) ion. As a result, the nitrate-containing mol-ecule contains disorder of its bidentate nitrate and two N-bound thio-cyanate anions, while the [Eu(NCS)3(OPPh3)3] complex is fully ordered. There is a weak π-π stacking inter-act...

In the title mononuclear salen-type complex, [Eu(NO(3))(3)(C(22)H(26)N(2)O(4))]·CH(3)OH, the Eu(III) ion is ten-coordinated by three bidentate nitrate counter-ions and one organic salen-type ligand, which acts in a bis-bidentate chelating mode through its phenolate and meth-oxy O atoms. The protonated imine groups are involved in intra-molecular N-H⋯O hydrogen bonds to the phenolate O atomss, e...

The asymmetric unit of title compound, [La(NO(3))(3)(C(15)H(15)NO(2))(2)(CH(3)OH)], consists of two Schiff base 2-meth-oxy-6-[(4-methyl-phen-yl)iminiometh-yl]phenolato (HL) ligands, three independent nitrate anions and one methanol mol-ecule coordinated to La(III). The coordination environment of the La(III) ion is formed by eleven O atoms. Three bidentate nitrate anions coordinate to the La(II...

The N-heterocycles in the centrosymmetric title compound, [La(2)(C(10)H(9)NO)(4)(CH(3)COO)(2)(NO(3))(4)], exist in the zwitterionic form. One heterocycle binds to a metal center whereas the other bridges two metal centers. Each La atom is chelated by an acetate and two nitrate groups and is surrounded by nine O atoms in a distorted tricapped trigonal-prismatic coordination environment. The N-H ...

In the title compound, [Mn(NO(3))(2)(C(7)H(9)NO)(2)], the Mn(II) atom (site symmetry 2) is coordinated by two N,O-bidentate (2-amino-phen-yl)methanol ligands and two monodentate nitrate anions in a distorted cis-MnN(2)O(4) octa-hedral coordination geometry. In the crystal, N-H⋯O, O-H⋯O and C-H⋯O hydrogen bonds help to establish the packing.
