(2,3-Di-2-pyridyl-pyrazine-?N,N)bis-(thio-cyanato-?S)palladium(II).

ABSTRACT: 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 dihedral angles of 70.3?(2) and 69.2?(1)°. The pyrazine ring is almost perpendicular to the PdS(2)N(2) plane, with a dihedral angle of 86.3?(1)°. The thio-cyanate ligands are located on opposite sides of the PdS(2)N(2) unit plane and are almost linear [N-C-S angles = 177.8?(6) and 178.9?(6)°]. The complex mol-ecules are stacked in columns along the b axis and are connected by inter-molecular C-H?N hydrogen bonds, forming chains along the a axis.

Mol-ecules are stacked in columns along the a axis. Along the b axis, successive mol-ecules stack in opposite directions.

Bis(di-2-pyridyl-amine-?N,N')bis-(thio-cyanato-?N)nickel(II).

Project description:The mononuclear neutral title complex, [Ni(NCS)(2)(C(10)H(9)N(3))(2)], shows a cis-octa-hedral geometry around the Ni(II) ion, formed by two chelating di-2-pyridyl-amine (Hdpa) ligands and two thio-cyanate anions. Both amine H atoms are involved in N-H?S hydrogen bonding, resulting in the formation of layers of inter-linked mol-ecules parallel to the ab plane, which are further held together by weak ?-? inter-actions between adjacent complexes, involving one ring of each dipyridyl-amine unit [centroid-centroid distance = 3.777?(4)?Å], forming a three-dimensional assembly.

Crystal structure of di-aqua-bis-(2,6-di-methyl-pyrazine-?N)bis-(thio-cyanato-?N)cobalt(II) 2,5-di-methyl-pyrazine tris-olvate.

Project description:In the crystal structure of the title compound, [Co(NCS)2(C6H8N2)2(H2O)2]·3C6H8N2, the Co(II) cation is coordinated by two terminally N-bound thio-cyanate anions, two water mol-ecules and two 2,6-di-methyl-pyrazine ligands, forming a discrete complex with a slightly distorted octa-hedral N4O2 coordination environment. The asymmetric unit contains one Co(II) cation and three halves of 2,5-di-methyl-pyrazine solvate mol-ecules, all entities being completed by inversion symmetry, as well as one thio-cyanate anion, an aqua ligand and a 2,6-di-methyl-pyrazine ligand, all in general positions. In the crystal, discrete complexes are arranged in a way that cavities are formed where the noncoordinating 2,5-di-methyl-pyrazine mol-ecules are located. The coordination of the latter to the metal is prevented due to the bulky methyl groups in vicinal positions to the N atoms, leading to a preferential coordination through the 2,6-di-methyl-pyrazine ligands. The complex mol-ecules are linked by O-H?N hydrogen bonds between the water H atoms and the N atoms of 2,5-di-methyl-pyrazine solvent mol-ecules, leading to a layered structure extending parallel to (100).
