Tris(thio-cyanato-?N)tris-(triphenyl-phosphine oxide-?O)terbium(III).

ABSTRACT: 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.

Project description: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].

Project description:In the title compound, [Ho(C(6)H(12)Cl(3)N(3)O(2)P)(3)(C(18)H(15)OP)], the Ho(III) ion is surrounded by six O atoms from the three bidentate N-[bis-(dimethyl-amino)phosphino-yl]-2,2,2-trichloro-acetamido ligands (L(-)) and by one O atom from the triphenyl-phosphine oxide ligand, with the formation of a distorted monocapped octa-hedron. In one ligand L(-), the trichloro-methyl group is rotationally disordered between two orientations in a 1:1 ratio, while two dimethyl-amino groups in another ligand L(-) are disordered between two conformations, each with the same 1:1 ratio.

Project description:In the title compound, (C7H11N2)3[Fe(NCS)6]·H2O, the Fe(III) cation is coordinated by six terminal N-bonded thio-cyanate anions into a discrete threefold negatively charged complex. Charge balance is achieved by three protonated 4-(dimethyl-amino)-pyridine cations. The asymmetric unit consists of one Fe(III) cation, six thio-cyanate anions, three 4-(dimethyl-amino)-pyridinium cations and one water mol-ecule, all of them located in general positions.

(Thio-cyanato-κS)-tris-(thio-urea-κS)mercury(II) chloride.

Project description:In the title salt, [Hg(NCS)(CH4N2S)3]Cl, the Hg(2+) ion is coordinated in a severely distorted tetra-hedral manner by three thio-urea groups and one thio-cyanate anion through their S atoms. The S-Hg-S angles vary widely from 87.39 (5) to 128.02 (4)°. Weak intra-molecular N-H⋯S hydrogen bonds are observed, which form S(6) ring motifs. In the crystal, the ions are linked by N-H⋯N and weak N-H⋯Cl inter-actions, generating a three-dimensional network.

Tris[6-meth-oxy-2-(phenyl-iminiometh-yl)phenolato]-?O,O';?O-tris-(thio-cyanato-?N)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.

Project description:The title compound, (C(19)H(15)N(4))(2)[Co(NCS)(4)], has two crystallographycally different molecules of bis-(2,3,5-triphenyl-tetra-zolium) tetra-thio-cyanatecobaltate in the asymmetric unit. There are only minor geometric differences between them. Each cobalt(II) ion is coordinated by the N atoms of four NCS anions, showing the magnitude of the magnetic moment expected from the NCS(-) crystal field strength.
