In the title compound, [Ni(C(13)H(16)NOS(2))(2)]·CH(3)CN, the Ni(II) atom is four-coordinated by two N,O-bidentate Schiff base ligands, resulting in a distorted tetra-hedral coordination for the metal ion.

In the title compound, [Li(CH(3)CN)(4)]PF(6)·CH(3)CN, the asymmetric unit consists of three independent tetra-hedral [Li(CH(3)CN)(4)](+) cations, three uncoordinated PF(6) (-) anions and three uncoordinated CH(3)CN solvent mol-ecules. The three anions are disordered over two sites through a rotation along one of the F-P-F axes. The relative occupancies of the two sites for the F atoms are 0.643...

The crystal structure of the title compound, (C(6)H(12)N(5)O)(4)[W(12)(SiO(4))O(36)]·6H(2)O, consists of an α-Keggin-type [W(12)(SiO(4))O(36)](4-) polyoxidoanion, four [(2H-tetra-zol-5-yl)meth-yl]morpholinium cations and six uncoordinated water mol-ecules.

In the structure of the title complex salt, (Et2NH2)2[CuCl4], the asymmetric unit consists of four unique di-ethyl-ammonium cations and three unique tetra-chlorido-cuprate anions. Two of the three anions are located with their copper atoms on independent crystallographic twofold axes, while the remaining tetra-chlorido-cuprate is located at a general position of the ortho-rhom-bic space group P...

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...

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...

The title compound, [Fe(C(6)H(4)N(5))(2)Cl(H(2)O)], was synthesized by hydro-thermal reaction of FeCl(3) with 2-(1H-tetra-zol-5-yl)pyridine. The iron(III) metal centre exhibits a distorted octa-hedral coordination geometry provided by four N atoms from two bidentate organic ligands, one water O atom and one chloride anion. The pyridine and tetra-zole rings are nearly coplanar [dihedral angles =...

The asymmetric unit of the title complex, [Co(H(2)O)(6)](C(9)H(10)N(8)O(4)S(2)), contains one-half of a [Co(H(2)O)(6)](2+) cation and one-half of a 5,5'-(propane-1,3-diyldithio)bis-(1H-tetra-zole-1-acetate) (battp(2-)) anion. The Co(II) center is coordinated by six H(2)O mol-ecules in a distorted octa-hedral coordination environment. In the crystal structure, intra- and inter-molecular O-H⋯O an...

The title compound, Cs(3)(Mo(2)O(7))Br, was synthesized by the reaction of CsNO(3), MoO(3) and 1-ethyl-3-methyl-imidazolium bromide. Its crystal structure is isotypic with K(3)(Mo(2)O(7))Br and contains (MoO(4))(2-) tetra-hedra which share an O atom to produce a [Mo(2)O(7)](2-) dimolybdate(VI) anion with a linear bridging angle and m2 symmetry. The anions are linked by Cs atoms (site symmetry m...

A guanidiniocarbonyl pyrrole (GCP) cation forms stable H-bond assisted ion pairs with carboxylates even in aqueous solutions. A tetra GCP cation 1 undergoes efficient two-component self-assembly with Na4EDTA, a tetra-carboxylate, leading to 3D supramolecular networks. These networks show dual pH responsiveness and reversibly dissociate back into monomers upon addition of either acid or base.
