The reaction of NiCl(2)·6H(2)O with sodium 2,2-dicyano-ethene-1,1-dithiol-ate [Na(2)(i-mnt)] in dimethyl sulfoxide produces the title complex, [Ni(C(2)H(6)OS)(6)][Ni(C(4)N(2)S(2))(2)]. There is half each of an [Ni(C(2)H(6)OS)(6)](2-) complex anion and an [Ni{(CH(3))(2)SO}(6)](2+) complex cation in the asymmetric unit. The i-mnt ligand coordinates in a bidentate manner to the Ni atom in the anio...

Metal complexes, ML (M=Ni, Cu, Co and Zn) of unsymmetrical tetradentate schiff base have been synthesized by the template reaction of the half-units N-(1-hydroxy-2-acetonaphthone)-1-amino-2-phenyleneimine)(HL1) with 2-Pyrroleca-rbaldehyde. The complexes have been characterized by elemental analysis, IR, 1H NMR and UV spectroscopy. The crystal structure of the Ni(II) complex has been determine...

The β-diketiminato nickel(I) complex K2[L(tBu)Ni(I)(N2(2-))Ni(I)L(tBu)] reacts with CO2 via reductive disproportionation to form CO and CO3(2-) containing products, whereas after employment of the Ni(I) precursor [L(tBu)Ni(I)(N2)Ni(I)L(tBu)] reductive coupling of CO2 was observed giving an oxalate bridged dinickel(II) complex. The addition of KC8 to the carbonate and oxalate compounds formed le...

The ionic title complex, [Ni(C(2)H(8)N(2))(3)](SiF(6)), is built up of [Ni(en)(3)](2+) complex cations (en = 1,2-diamino-ethane) and hexa-fluoridosilicate anions. Single crystals of the title complex were isolated from an aqueous-ethano-lic Ni(2+)-en-SiF(6) (2-) system. The Ni(II) and Si atoms are each located on a special position with site symmetry 3.2. The Ni(II) atom coordination sphere is ...

The ionic Ni(II) title complex, [Ni(C(3)H(10)N(2))(2)(H(2)O)(2)][Ni(SO(4))(2)(C(3)H(10)N(2))(2)], is built up of [Ni(dipr)(2)(H(2)O)(2)](2+) complex cations and [Ni(dipr)(2)(SO(4))(2)](2-) complex anions (dipr is propane-1,3-diamine). Both Ni(II) atoms display a slightly distorted octa-hedral coordination and are located on inversion centers. There are several types of hydrogen-bonding inter-ac...

Reaction of the pincer hydride complex ((tBu)PCP)Ni(H) [(tBu)PCP = 2,6-C(6)H(3)(CH(2)P(t)Bu(2))(2)] with BH(3)·thf in THF at 190 K generates the corresponding borohydride complex ((tBu)PCP)Ni(BH(4)). The kinetically stable (but thermodynamically unstable) species undergoes reversible borane loss. The related fluoride complex ((tBu)PCP)Ni(F) shows the same reactivity towards BF(3)·Et(2)O, produc...

Oxidations of a trigonal-bipyramidal, high-spin Ni(II) dithiolate complex of a pentadentate, N3S2-donor ligand, N1,N9-bis(imino-2-mercaptopropane)-1,5,9-triazanonane) nickel(II), and the structurally analogous Zn(II) complex, lead to oxidations of the ligand. Oxidation of the Ni(II) complex with I2 produces a novel Ni(II) macrocyclic cationic complex containing a monodentate disulfide ligand (2...

Herein, we report a novel polymerized-complex method for the preparation of Ni-Pd, Ni-Pt, and Cu-Pt alloys and Pt, Pd, Ag, Ni, and Cu nanoparticles. The grain sizes and crystalline phases of these nanoparticles can be controlled. These nanoparticles are obtained via the formation of a polymerized complex and release of reducing gases during N2-protected calcination.
