چکیده
The asymmetric unit of the title compound, [Zn(NCSe)(2)(C(4)H(4)N(2))(2)](n), consists of one Zn(2+) cation located on a special position with site symmetry 2/m, one seleno-cyanate anion on a mirror plane and one pyrimidine ligand on a twofold rotation axis. The zinc cation is coordinated by six N atoms of four pyrimidine ligands and two N-bonded seleno-cyanate anions in mutually trans orientations within a slightly distorted octa-hedral coordination environment. The Zn atoms are μ-1,3-bridged via the pyrimidine ligands into a polymeric layer extending parallel to (100).

In the title complex, {[Cu3[W(CN)8]2(C5H6N2)4(H2O)2]·2H2O} n , the coordination polyhedron of the eight-coordinated W(V) atom is a bicapped trigonal prism, in which five CN groups are bridged to Cu(II) ions, and the other three CN groups are terminally bound. Two of the Cu(II) ions lie on a centre of inversion and each of the three independent Cu(II) cations is pseudo-octahedrally coordinated. ...

The title compound, [Na2(C6H18NSi2)2(C6H16N2)] n , was found to consist of dimeric [Na(NSiMe3)2] units with crystallographically imposed centrosymmetry based upon four-membered NaNNaN rings. The dimers are bridged by N,N,N',N'-tetra-methyl-ethylenediamine ligands, which act in an unusual extended non-chelating coordination mode. This gives a one-dimensional coordination polymer that extends par...
