In the title polymeric complex, [Ni(C(2)H(6)NO(3)S)(2)](n), the Ni(II) ion occupies a special position on an inversion centre and displays a slightly distorted octa-hedral coordination geometry, being linked to four sulfonate O atoms and to two N atoms of the taurine ligands. The sulfonate groups doubly bridge symmetry-related Ni(II) centers, forming polymeric chains along the a axis.

Complex engineered nanomaterials (CENs) are a rapidly developing class of structurally and compositionally complex materials that are expected to dominate the next generation of functional nanomaterials. The development of methods enabling rapid assessment of the toxicity risk associated with this type of nanomaterial is therefore critically important. We evaluated the toxicity of three differe...

In the title compound, [Ni(C(45)H(34)BN(6))(C(10)H(9)N(3))]Br·CH(2)Cl(2), the Ni(II) atom is five-coordinated by the tridentate hydro-tris-(3,5-diphenyl-pyrazol-yl)borate ligand and a bidentate di-2-pyridyl-amine ligand in a distorted square-pyramidal geometry. In the crystal, inter-molecular N-H⋯Br and C-H⋯Br hydrogen bonds link the Ni complex cations and the Br(-) ions, forming a chain along ...

The O and N atoms of the morpholine substituent in the ligand are not involved in coordination to the Ni atom.

The title trinuclear complex, [Ni(3)(C(9)H(7)N(2)O(4))(2)(C(5)H(5)N)(8)], possesses a crystallographically imposed center of symmetry occupied by one Ni(II) ion. Each of the three Ni(II) ions is coordinated by two O and four N atoms, respectively, in a distorted octa-hedral geometry. In the crystal, weak inter-molecular C-H⋯π inter-actions link the mol-ecules into ribbons propagating in the [10...

In the title complex, [Ni(CH(3)CN)(2)(C(3)H(4)N(2))(4)](NO(3))(2), the cation lies on an inversion center and adopts an octa-hedral coordination geometry about the Ni atom. The two acetonitrile ligands are in a trans conformation. N-H⋯O hydrogen bonds between cations and anions link the complex mol-ecules into one-dimensional chains running parallel to [100].

The mol-ecular structure of the title complex, [Ni2(C11H13NO3)2]·CH3OH, contains two Ni(II) atoms and two doubly deprotonated 6-meth-oxy-2-{[(3-oxidoprop-yl)imino]-meth-yl}phenolate ligands. The Ni(II) atoms are each four-coordinated in a distorted square-planar geometry by three O atoms and one N atom derived from the phenolate ligands. The solvent mol-ecule is linked to the complex mol-ecule ...
