Bis(pyridazine-?N)bis-(seleno-cyanato-?N)zinc.

ABSTRACT: The asymmetric unit of the title compound, [Zn(NCSe)(2)(C(4)H(4)N(2))(2)], consists of one Zn(II) cation, located on a twofold rotation axis, one seleno-cyanate anion and one pyridazine ligand in general positions. The Zn(II) atom is coordinated by two N-atoms of two pyridazine ligands and two terminal N-bonded seleno-cyanate anions within a slightly distorted tetra-hedral coordination environment. In the crystal, discrete complex mol-ecules are arranged in layers parallel to the ac plane, with Zn(II)?Zn(II) distances of 8.0906?(6)?Å along the a axis and of 9.0490?(7) or 9.3604?(7)?Å along the c axis. The complex mol-ecules are further linked via weak Se?Se inter-actions, with Se?Se distances of 3.8235?(9)?Å.

Project description: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 arranged into layers parallel to (001). These layers are separated by additional non-coordinating pyridazine ligands.

Tetra-kis(pyridazine-?N)bis-(seleno-cyanato-?N)nickel(II) pyridazine disolvate.

Project description:The reaction of nickel(II) nitrate with potassium seleno-cyanate and pyridazine leads to crystals of the title compound, [Ni(NCSe)(2)(C(4)H(4)N(2))(4)]·2C(4)H(4)N(2). The Ni(II) atom is coordinated by two terminal N-bonded seleno-cyanate anions and four pyridazine ligands within a slightly distorted octa-hedral geometry. The crystal structure contains two crystallographically independent pyridazine molecules in cavities of the structure, which are not coordinated to the metal centres. The structure is pseudo-C-centered due to the positioning of the discrete coordination complexes; the non-coordinating pyridazine molecules, however, break the C-centering. In the subcell, these ligands are disordered around centres of inversion, which do not coincide with the mid-point of the mol-ecules.
