چکیده
The title complex, [Ni(C(10)H(10)N(6))(2)][Ni(CN)(4)]·2H(2)O, contains an octa-hedral nickel(II) cation and a square-planar nickel(II) anion. Both the cation and the anion reside on a crystallographic center of inversion. The Ni(II) center in the cation is coordinated by six pyrazol-1-yl rings of two chelating tripyrazol-1-ylmethane [HC(pz)(3)] ligands, with Ni-N distances that range between 2.0647 (19) and 2.0828 (19) Å. The Ni(II) center in the anion is coordinated by four cyanide ligands, with Ni-C distances in the range 1.869 (2)-1.869 (3) Å. The [Ni(CN)(4)](2-) anions are linked by inversion-related water mol-ecules into extended chains that run parallel to the a axis.

In this paper, nickel oxide (NiO) nanoparticles have been prepared by solid state thermal decomposition of an acyclic nickel(II) complex (1,2-bis(2-formyl-3-methoxyphenyl)propane)nickel(II) chloride, [NiL]Cl2, in an electrical furnace at optimal temperature, 450 ºC for 3.5 h. The nickel(II) complex is obtained via solid state synthesis using nickel(II) chloride and tetradentate O4 acyclic ligan...

In the title compound, [Ni(C(24)H(16)N(6))(2)](NCS)(2)·2H(2)O, the central Ni(II) ion is octahedrally coordinated by six N atoms of two tridentate 2,3,5,6-tetra-2-pyridyl-pyrazine ligands (tppz). Two thio-cyanate anions act as counter-ions and two water mol-ecules act as solvation agents. O-H⋯N hydrogen bonds are observed in the crystral structure.

In the title layer complex, {[Ni(C(8)H(4)O(4))(C(10)H(8)N(2))(H(2)O)(2)]·2H(2)O}(n), the Ni atom has a distorted octa-hedral environment, defined by the phthalate and 4,4'-bipyridyl ligands which link the Ni atoms, forming a square lattice in the bc plane. This extends into a three-dimensional supra-molecular network through O-H⋯O hydrogen-bonding inter-actions. The Ni atom lies on, and both li...

The title compound, [Ni(C(5)H(7)O(2))(2)(C(5)H(5)N)(2)]·2H(2)O, crystallizes with two half-mol-ecules in the asymmetric unit. The Ni(II) ion of each unique complex mol-ecule lies on an inversion centre and has an octa-hedral coordination geometry. The crystal structure features weak O-H⋯O hydrogen bonds, which form chains running parallel to the a axis.
