(2,2'-Bipyrimidine-?(2)N(1),N(1'))bis-(thio-cyanato-?N)platinum(II).

ABSTRACT: In the title complex, [Pt(NCS)(2)(C(8)H(6)N(4))], the Pt(II) ion is four-coordinated in a distorted square-planar environment defined by two pyrimidine N atoms derived from a chelating 2,2'-bipyrimidine (bpym) ligand and two mutually cis N atoms from two SCN(-) anions. The thio-cyanate ligands are almost linear, displaying N-C-S bond angles of 178.6?(11) and 173.7?(11)°, and the N atoms are slightly bent coordinated to the Pt atom with Pt-N-C bond angles of 172.7?(9) and 160.4?(10)°. In the crystal, mol-ecules are held together by C-H?S hydrogen bonds. Intra-molecular C-H?N hydrogen bonds are also observed.

Project description:The asymmetric unit of the title compound, K(2)[Pd(NCS)(4)]·2[Pd(NCS)(2)(C(8)H(6)N(4))], contains two crystallographically independent half-mol-ecules of the anionic Pd(II) complex, two K(+) cations and two independent neutral Pd(II) complexes; an inversion centre is located at the centroid of each anionic complex. In the anionic complexes, each Pd(II) ion is four-coordinated in an almost regular square-planar environment by four S atoms from four SCN(-) anions, and the PdS(4) unit is exactly planar. In the neutral complexes, the Pd(II) ion has a slightly distorted square-planar coordination environment defined by two pyrimidine N atoms derived from a chelating 2,2'-bipyrimidine ligand and two mutually cis S atoms from two SCN(-) anions. Both 2,2'-bipyrimidine ligands are almost planar [dihedral angle between the rings = 3.98?(16) and 4.57?(17)°] and also chelate to a potassium ion from their other two N atoms. In the crystal, the K(+) ions inter-act with various S and N atoms of the ligands, forming a three-dimensional polymeric network, in which the shortest K?K contacts between the KN(7)S polyhedra are 4.4389?(17) and 4.4966?(18)?Å. Intra- and inter-molecular C-H?S and C-H?N hydrogen bonds are also observed.

Bis(2,2'-bipyridine-κN,N')(thio-cyanato-κN)copper(II) perchlorate.

Project description:The asymmetric unit of title compound, [Cu(NCS)(C(10)H(8)N(2))(2)]ClO(4), contains a bis-(2,2'-bipyridine)(isothio-cyanato)copper(II) cation and a perchlorate anion. In the cation, the Cu(2+) ion is coordinated by four N atoms from two bidentate 2,2'-bipyridine mol-ecules and an N atom from an isothio-cyanate anion, resulting in a distorted CuN(5) pyramidal configuration. The crystal structure is stabilized by weak inter-molecular C-H⋯O and C-H⋯S hydrogen bonds, and weak π-π inter-actions between 2,2'-bipyridine rings [centroid-centroid distance = 3.908 (4) Å]. The perchlorate counteranion is disordered over two positions in a 0.66:0.34 ratio.

Crystal structure of bis-(2,2'-bi-pyridine-κ(2) N,N')bis-(thio-cyanato-κN)mang-anese(II) 2,2'-bi-pyridine monosolvate.

Project description:In the crystal structure of the mononuclear title compound, [Mn(NCS)2(C10H8N2)2]·C10H8N2, the Mn(II) cation is coordin-ated in an all-cis configuration by two N-bound thio-cyanate anions and two 2,2'-bi-pyridine ligands within a slightly distorted octa-hedral environment. The asymmetric unit consists of one Mn(II) cation, two thio-cyanate anions and two 2,2'-bi-pyridine ligands, as well as two non-coordinating 2,2'-bi-pyridine ligands that are each located on centres of inversion. In the crystal structure, the discrete [Mn(NCS)2(C10H8N2)2] complex mol-ecules are arranged in such a way that cavities are formed, in which the solvent 2,2'-bi-pyridine mol-ecules are located. Apart from van der Waals forces, there are no remarkable inter-molecular inter-actions present in the crystal structure.

Crystal structure of bis-(thio-cyanato-?S)bis-(thio-urea-?S)mercury(II).

Project description:In the title complex, [Hg(NCS)2(CH4N2S)2], the Hg(II) atom is four-coordinated having an irregular four-coordinate geometry composed of four thione S atoms of two thio-cyanate groups and two thio-urea groups. The S-Hg-S angles are 172.02?(9)° for the trans-thio-cyanate S atoms and 90.14?(5)° for the cis-thio-urea S atoms. The mol-ecular structure is stabilized by an intra-molecular N-H?S hydrogen bond, which forms an S(6) ring motif. In the crystal, mol-ecules are linked by a number of N-H?N and N-H?S hydrogen bonds, forming a three-dimensional framework. The first report of the crystal structure of this compound appeared in 1966 [Korczynski (1966 ?). Rocz. Chem. 40, 547-569] with an extremely high R factor of 17.2%, and no mention of how the data were collected.

Crystal structures of tetra-kis-(pyridine-4-thio-amide-?N)bis-(thio-cyanato-?N)cobalt(II) monohydrate and bis-(pyridine-4-thio-amide-?N)bis-(thio-cyanato-?N)zinc(II).

Project description:Reaction of Co(NCS)2 and Zn(NCS)2 with 4-pyridine-thio-amide led to the formation of compounds with composition [Co(NCS)2(C6H6N2S)4]·H2O (1) and [Zn(NCS)2(C6H6N2S)2] (2), respectively. The asymmetric unit of compound 1, consists of one cobalt(II) cation, two thio-cyanate anions, four 4-pyridine-thio-amide ligands and one water mol-ecule whereas that of compound 2 comprises one zinc(II) cation that is located on a twofold rotation axis as well as one thio-cyanate anion and one 4-pyridine-thio-amide ligand in general positions. In the structure of compound 1, the cobalt(II) cations are octa-hedrally coordinated by two terminal N-bonding thio-cyanate anions and by the N atoms of four 4-pyridine-thio-amide ligands, resulting in discrete and slightly distorted octa-hedral complexes. These complexes are linked into a three-dimensional network via inter-molecular N-H?S hydrogen bonding between the amino H atoms and the thio-cyanate S atoms. From this arrangement, channels are formed in which the water mol-ecules are embedded and linked to the host structure by inter-molecular O-H?S and N-H?O hydrogen bonding. In the structure of compound 2, the zinc(II) cations are tetra-hedrally coordinated by two N-bonding thio-cyanate anions and the N atoms of two 4-pyridine-thio-amide ligands into discrete complexes. These complexes are likewise connected into a three-dimensional network by inter-molecular N-H?S hydrogen bonding between the amino H atoms and the thio-amide S atoms.

Di-?-thio-cyanato-?N:S;?S:N-bis-[bis-(2-methyl-1H-benzimidazole-?N)(thio-cyanato-?N)cadmium(II)].

Project description:The title compound, [Cd(2)(NCS)(4)(C(8)H(8)N(2))(4)], is a centrosymmetric dinuclear cadmium(II) complex in which each two metal ions are linked by a pair of thio-cyanate N:S-bridges. Two 2-methyl-benzimidazole N-atom donors and one terminal thio-cyanate N atom complete a highly distorted square-pyramidal geometry around the Cd atom. In the crystal structure, two N-H?S hydrogen-bonding inter-actions occur, resulting in a three-dimensional polymeric structure. The apical 2-methyl-benzimidazole ring and its symmetry-related counterpart are arranged in an anti-parallel manner with a centroid-centroid separation of 3.6050?(14)?Å, indicative of a ?-? inter-action.
