Axial ligand substitution of a mononuclear nonheme oxoiron(IV) complex, [FeIV(O)(TMC)(NCCH3)]2+ (1) (TMC = 1,4,8,11-tetramethyl-1,4,8,11-tetraazacyclotetradecane), leads to the formation of new FeIV=O species with relatively intense electronic absorption features in the near-UV region. The presence of these near-UV features allowed us to make the first observation of Fe=O vibrations of S = 1 mo...
The title compound, [NiCl 2 (C 4 H 6 N ) ]·2CH 3 CN, is a mononuclear octahedral Ni II pyrazole-based complex. Two acetonitrile molecules are linked to the complex by N—H...N hydrogen bonds. atom octahedrally coordinated four atoms of 4-methyl-1 -pyrazole ligands, forming equatorial plane. axial positions occupied two Cl atoms. CN was synthesized reaction with nickel(II) chloride hexahydrate in...
Treatment of [PdCl2(PhCN)2] with diaryl telluride in 1 : 2 molar ratio gave mononuclear palladium complexes, trans-[PdCl2(TeR2)2] () (R = Mes () (Mes = 2,4,6-trimethylphenyl), Ph (), o-tol () (o-tol = ortho-tolyl)). Reaction of [PdCl2(TeMes2)2] with one equivalent of [PdCl2(PhCN)2] or Na2PdCl4 with TeRR' afforded chloro-bridged binuclear complexes, [Pd2(μ-Cl)2Cl2(TeRR')2] () (R/R' = Mes/Mes ();...
In the mononuclear title complex, [Ag(C(10)H(6)N(4))(2)]PF(6), two κ(2)N,N'-chelating 5-(pyridin-2-yl)pyrazine-2-carbonitrile ligands surround the Ag(I) atom, forming a distorted N(4) tetra-hedral coordination geometry. The mononuclear units are inter-connected through π-π inter-actions [centroid-centroid distances = 3.801 (2) and 3.979 (3) Å] and the hexa-fluoridophosphate anions are embedded ...
In vivo administration of escalation doses of recombinant alpha-interferon (IFN-alpha) during a phase I trial in malignant melanoma patients caused dose-dependent increases in the mRNA accumulation, synthesis, steady state cellular content, and plasma membrane expression of class I major histocompatibility complex molecules in peripheral blood mononuclear cells. In addition, circulating levels ...
