In the crystal structure of the title compound, [Cd(NCS)2(C9H13N)2] n , the Cd(II) cations are coordinated in a slightly distorted octa-hedral geometry by one 3-tert-butyl-pyridine ligand, one 4-tert-butyl-pyridine ligand and two pairs of translationally-equivalent μ-1,3-bridging thio-cyanate ligands, all of which are in general positions. These μ-1,3-bridging thio-cyante anions bridge the Cd(I...

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 sy...

The asymmetric unit of the title mononuclear Ni(II) compound, [Ni(NCS)(2)(C(8)H(12)N(2))(2)], contains two independent half-mol-ecules, the Ni atoms of which lie on crystallographic inversion centres. Each Ni(II) ion is chelated by two N atoms from two N-phenyl-ethane-1,2-diamine ligands and is also coordinated by two N atoms from two thio-cyanate ligands, giving a distorted octa-hedral geometr...

In the crystal structure of the title compound, [Fe(3)(NCS)(6)(C(4)H(4)N(2))(8)](n), each iron(II) cation is coordinated by four N-bonded pyrimidine ligands and two N-bonded thio-cyanate anions in a distorted octa-hedral environment. The asymmetric unit consists of one iron cation located on a crystallographic center of inversion, as well as one iron cation, three thio-cyanate anions and four p...

The title compound, [Ag(NCS)(C(25)H(22)P(2))](n), contains two Ag(+) ions, two thio-cyanate ions and two bis-(diphenyl-phosphino)methane (dppm) ligands in the asymmetric unit. One of the thiocyanate ions bridges the two Ag(+) ions in a μ(2)-mode from its S atom and the two dppm ligands bridge the silver ions in a μ(1),μ(1) mode. The remaining SCN(-) ion bridges the binuclear units via its N and...

The Sn(IV) atom in the centrosymmetric title complex, [Sn2(CH3)4(NCS)2(OH)2], adopts a distorted trigonal-bipyramidal coordination environment defined by two methyl C atoms and one bridging hydroxide group in the equatorial plane while the other bridging hydroxide group and the N atom of the thio-cyanate anion are in the apical >positions. The dinuclear species are linked through O-H⋯S and C-H⋯...

A new polymorph of the title compound, [Re(NCS)(C7H8N2O)(CO)3], crystallizing in the space group P21/n, has been obtained and structurally characterized by the experiment and DFT calculations. In this complex, the rhenium(I) cation is octa-hedrally coordinated by three carbonyl groups in a facial configuration, the N,O-bidentate N-methyl-pyridine-2-carboxamide ligand and the N-bonded thio-cyana...

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 wa...
