Tris(thio-cyanato-?N)tris-(triphenyl-phosphine oxide-?O)europium(III)-(nitrato-?(2) O,O')bis-(thio-cyanato-?N)tris-(triphenyl-phosphine oxide-?O)europium(III) (1/1).

ABSTRACT: 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 ?-? stacking inter-action between the phenyl rings of the two mol-ecules [centroid-centroid distance = 4.138?(4)?Å].

Tris(thio-cyanato-κN)tris-(triphenyl-phosphine oxide-κO)terbium(III).

Project description:The title compound, [Tb(NCS)3(C18H15OP)3], contains a six-coordinate Tb(II) cation surrounded by three O-bound triphenyl-phosphine oxide ligands and three N-bound thio-cyanate ligands, each in a fac arrangement. There are two crystallographically unique Tb(III) atoms in the asymmetric unit. One Tb(III) atom resides on a threefold rotation axis, while the other has no imposed crystallographic symmetry. The thio-cyanate ligands are bound through N atoms, illustrating the hard-hard bonding principles of metal complex chemistry.

Tris{2-meth-oxy-6-[(4-methyl-phen-yl)iminiometh-yl]phenolate-κO,O'}tris-(thio-cyanato-κN)europium(III).

Project description:The metal center in the structure of the title compound, [Eu(NCS)(3)(C(15)H(15)NO(2))(3)], is coordinated by three Schiff base 2-meth-oxy-6-[(4-methyl-phen-yl)iminiometh-yl]phenolate (L) ligands and three independent thio-cyanate 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 Eu(III) ion is nine-coordinate by three chelating methoxy-phenolate pairs of O atoms and three N-atom terminals of the thio-cyanate ions. The compound is isostructural with the Ce(III) analogue [Liu et al. (2009 ▶). Acta Cryst. E65, m650].

Tris[6-meth-oxy-2-(phenyl-iminiometh-yl)phenolato]-κO,O';κO-tris-(thio-cyanato-κN)samarium(III).

Project description:In the crystal structure of title compound, [Sm(NCS)(3)(C(14)H(13)NO(2))(3)], two of the zwitterionic Schiff base 6-meth-oxy-2-(phenyl-iminiometh-yl)phenolate ligands coordinate to the Sm(III) atom in a bidentate fashion via the phenolate and meth-oxy O atoms. The third Schiff base ligand is monodentate, binding only through the phenolate O atom. The coordination sphere of the eight-coordinate Sm atom is completed by the three independent thio-cyanate ions binding through their N atoms, affording a square-anti-prismatic geometry. An S atom of one of the thio-cyanate anions is disordered over two sites in a 0.85:0.15 ratio. In the phenolate ligands, the proton of the phenolic hy-droxy group transfers to the imine N atom. This proton is also involved in an intra-molecular N-H⋯O hydrogen bond that imposes a nearly planar conformation on each ligand, with dihedral angles of 1.75 (4), 3.68 (5) and 3.86 (4)° between the aromatic rings of each ligand.

Bis(acetyl-acetonato-κO,O')(methanol-κO)(thio-cyanato-κN)manganese(III).

Project description:In the title complex, [Mn(C(5)H(7)O(2))(2)(NCS)(CH(4)O)], the Mn(III) atom has a slightly distorted octa-hedral coordination formed by five O atoms and one N atom. The equatorial positions are occupied by four O atoms of two acetyl-acetonate ligands, while the axial positions are occupied by the N atom of the thio-cyanate anion and the O atom of the methanol mol-ecule. In the crystal structure, complex mol-ecules are linked by an inter-molecular O-H⋯S hydrogen bond, forming a chain running along [101].

Project description:In the title compound, [Nd(NCS)(3)(C(15)H(15)NO(2))(3)], the Nd(III) ion is coordinated by three thio-cyanate anions [Nd-N = 2.489 (8)-2.530 (7) Å] and six O atoms [Nd-O = 2.375 (4)-2.843 (5) Å] from three zwitterionic 2-meth-oxy-6-(4-methyl-phenyl-iminiometh-yl)phenolate ligands in a tricapped trigonal-prismatic geometry. Intra-molecular N-H⋯O hydrogen bonds occur. The crystal packing exhibits weak inter-molecular C-H⋯S hydrogen bonds, π-π inter-actions with a distance of 3.904 (7) Å between the centroids of the aromatic rings, and voids of 101 Å(3).

The layers are connected via weak O-H⋯S hydrogen bonding.
