The title three-dimensional coordination polymer, [Cu(2)Cl(C(6)H(4)N(5))](n), is the product of the hydro-thermal reaction of CuCl(2)·2H(2)O and 5-(4-pyrid-yl)-1H-tetra-zole (4-Hptz). The two independent Cu(I) ions are coordinated in distorted tetra-hedral and distorted trigonal coordination environments. In the unique 5-(4-pyrid-yl)-1H-tetra-zolate ligand, the dihedral angle between the pyridi...

The title compound, C(24)H(46)N(4)O(8) (2+)·2Cl(-)·2H(2)O, was synthes-ized by the hydrolysis of tetra-ethyl 2,2',2'',2'''-(5,5,7,12,12,14-hexa-methyl-1,4,8,11-tetra-azacyclo-tetra-decane-1,4,8,11-tetra-yl) tetra-acetate in hydro-chloric acid solution. The crystal structure of the title compound consists of a 14-membered C(10)N(4) centrosymmetric cationic macrocycle which inter-acts with the ch...

Tetra-n-butylammonium bromide forms the title semi-clathrate hydrate crystal, C16H36N+.Br-.38H2O, under atmospheric pressure. The cation and anion lie at sites with mm symmetry and seven water molecules lie at sites with m symmetry in space group Pmma. Br- anions construct a cage structure with the water molecules. Tetra-n-butylammonium cations are disordered and are located at the centre of fo...

The title complex, [Li4(C17H14N4)2(C4H8O)4], bears a novel tetra-dentate di-amido ligand. In the tetra-nuclear centrosymmetric complex mol-ecule, the metal atoms exhibit two kinds of coordination modes. The middle two Li(+) cations are coord-inated by four N (ligand) and one O (tetra-hydro-furan, THF) atoms, resulting in a distorted square-pyramidal geometry. The outer two Li(+) cations are in ...

In the title complex, [Ni(C₃₆H₂₆Cl₄N₄O₂)]·C₃H₆O, two 2,4-dichloro-benzoyl groups are grafted onto the methine groups of the Ni(II) complex Ni(tmtaa) (H₂tmtaa = 5,7,12,14-tetra-methyl-4,11-dihydro-dibenzo[b,i][1,4,8,11]tetra-aza-cyclo-tetra-decine). The complex has the shape of a saddle. The Ni atom is tetra-coordinated by the four N atoms of the macrocycle, forming a slightly tetra-hedrally dis...

In the title complex, [Zn(C(5)H(9)N(4))(2)](n), the Zn(II) center is coordinated by four N atoms of different tetra-zolate ligands with a slightly distorted tetra-hedral geometry [Zn-N distances and N-Zn-N angles are in the ranges 1.991 (2)-2.007 (2) Å and 104.22 (8)-116.13 (8)°, respectively]. Each ligand links two Zn(II) atoms through its 1- and 4-position tetra-zole N atoms, forming a single...

In the title compound, [Zn(C(11)H(8)N(5)O)(N(3))](n), the Zn atom is hexa-coordinated by five N atoms and one O atom in a distorted octa-hedral geometry. The chelating 5-(8-quinolyloxymeth-yl)tetra-zolate ligands are approximately planar, with a dihedral angle of 3.6 (2)° between the quinoline and tetra-zole planes. Adjacent Zn atoms are linked by two bridging azide ligands across a centre of i...
