Reaction of cobalt(II) nitrate with potassium seleno-cyanate and pyridazine leads to single crystals of the title compound, [Co(NCSe)(2)(C(4)H(4)N(2))(4)]·2C(4)H(4)N(2), which is isotypic with its nickel(II) thio-cyanate analogue. The Co(2+) cations are coordinated by two N-bonded seleno-cyanate ligands and four N atoms from four pyridazine ligands into discrete complexes. The complexes are arr...

In the crystal structure of the title compound, [Co(NCSe)(2)(C(7)H(7)NO)(2)(H(2)O)(2)], the Co(2+) cation is coordinated by two seleno-cyanate anions, two 3-acetyl-pyridine ligands and two water mol-ecules within a slightly distorted CoN(4)O(2) octa-hedron. The asymmetric unit consists of one Co(2+) cation, which is located on a center of inversion, as well as one seleno-cyanate anion, one 3-ac...

The Pd(II) ion in the title complex, [Pd(NCS)(2)(C(14)H(10)N(4))], is four-coordinated in a distorted square-planar environment by the two pyridine N atoms of the chelating 2,3-di-2-pyridyl-pyrazine (dpp) ligand and two S atoms from two thio-cyanate anions. The pyridine rings are considerably inclined to the least-squares plane of the PdS(2)N(2) unit [maximum deviation = 0.027 (1) Å], making di...

In the mononuclear title complex, [Ni(NCS)(2)(C(14)H(22)N(2)O(2))(2)], the Ni atom lies on an inversion centre. It is chelated by the phenolate O and imine N atoms from two zwitterionic Schiff base ligands, and is also coordinated by the N atoms from two thio-cyanate ligands, giving a slightly distorted octa-hedral geometry. Intra-molecular N-H⋯O and N-H⋯N hydrogen bonds are observed.

In the title one-dimensional coordination polymer, [Mn(NCS)(3)(C(10)H(16)N(3))](n), the Mn(II) atom is coordinated by an N,N'-bidentate Schiff base and four thio-cyanate ligands in a distorted octa-hedral N(5)S geometry. Bridging thio-cyanate ligands inter-connect adjacent [Mn(NCS)(2)(C(10)H(16)N(3))] units, giving rise to helical chains extending along the b axis. The chains are further linked...

In the title compound, [Co(C6H5NO2)(NCS)(C6H4NO2)] n , the Co(2+) cation is coordinated by one N and two O atoms of three bridging pyridine-4-carboxyl-ate anions, one O atom of one zwitterionic pyridinium-4-carboxyl-ate ligand and one terminal N-bonding thio-cyanate anion within a distorted N2O3 trigonal bipyramid. The bridging coordination mode of the ligands leads to the formation of layers p...

In the title compound, C14H15BrN2O2S, synthesized by the reaction of the corresponding phenacyl thio-cyanate with morpholine, the dihedral angle between the 1,3-thia-zole ring and the phenolic substituent ring is 23.46 (10)° as a result of the steric influence of the ortho-methyl group on the thia-zole ring. A strong intra-molecular phenolic O-H⋯N hydrogen bond is present in the mol-ecule. In t...

In the title compound, [Au(2)Ba(NCS)(4)(C(20)H(24)O(6))](n), the dithio--cyanato-aurate(I) anion adopts a dimeric structure with an Au⋯Au distance of 3.1109 (10) Å; both Au(I) atoms are also bonded to two S atoms. The Ba(II) ion adopts an irregular BaN(3)O(6) geometry, arising from the crown ether and three adjacent thio-cyanate N atoms; the extended structure of the complex can be described as...

In the title compound, [Co(NCS)(2)(C(11)H(13)NO(2))(2)], a mononuclear Schiff base cobalt(II) complex, the Co atom is six-coordinated by four O atoms from two Schiff base ligands, and by two N atoms from two thio-cyanate ligands, forming a distorted octa-hedral geometry. The central Co atom lies on a twofold rotation axis. An intramolecular N-H⋯O hydrogen bond is present.

The asymmetric unit of the title complex, [Ni(NCS)(2)(C(13)H(20)N(2)O(2))(2)], consists of two half-mol-ecules, both of which are completed by crystallographic inversion symmetry (Ni(2+) site symmetry = in both cases). Both metal ions are six-coordinated in distorted trans-NiO(2)N(4) geometries arising from two N,O-bidentate Schiff base ligands and two N-bonded thio-cyanate ions. The mol-ecular...
