Low valent carbonylvanadium complexes of the triphosphorus macrocycle 12[ane]P3Et3
The triphosphorus macrocycle 1,5,9-triethyl-1,5,9-triphosphacyclododecane, 12[ane]P3Et3, reacts with [V(CO)6] under photolytic conditions to produce fac-[(12[ane]P3Et3)V(CO)3] (1) which has been isolated as its Et4N salt. This can be oxidised to the neutral 17 electron complex fac-(12[ane]P3Et3)V(CO)3 (2), which has been characterised by EPR spectroscopy. Density functional calculations support...
متن کاملUnexpected neutral aza-macrocycle complexes of sodium.
Highly unusual Na(+) complexes with neutral tri- and tetra-amines are isolable in good yield from the reaction of NaBAr(F) with the amine in organic media. Structural characterisation reveals primary Na-N bonding, including an unusual sandwich cation [Na(Me3tacn)2](+), derived from homoleptic N6-coordination via two Me3-tacn ligands, and the distorted 5-coordinate [Na(thf)(Me4cyclam)](+).
متن کاملComplexes of a porphyrin-like N4-donor Schiff-base macrocycle.
A metal-free 16-membered N4-donor [1 + 1] Schiff-base macrocycle was isolated as HL(Pr)·2acid, by 1 : 1 condensation of diphenylamine-2,2'-dicarboxaldehyde (1), dipropylene triamine and an excess of either acetic or formic acid, or as HL(Pr)·(tosylic acid) when just one equivalent of tosylic acid was employed. Interestingly, the acid-free synthesis employed for the 14-membered analogue HL(Et) f...
متن کاملCationic cluster formation versus disproportionation of low-valent indium and gallium complexes of 2,2'-bipyridine
Group 13 M(I) compounds often disproportionate into M(0) and M(III). Here, however, we show that the reaction of the M(I) salt of the weakly coordinating alkoxyaluminate [Ga(I)(C6H5F)2](+)[Al(OR(F))4](-) (R(F)=C(CF3)3) with 2,2'-bipyridine (bipy) yields the paramagnetic and distorted octahedral [Ga(bipy)3](2+)(•){[Al(OR(F))4](-)}2 complex salt. While the latter appears to be a Ga(II) compound, ...
متن کاملDetection of bacterial spores with lanthanide-macrocycle binary complexes.
The detection of bacterial spores via dipicolinate-triggered lanthanide luminescence has been improved in terms of detection limit, stability, and susceptibility to interferents by use of lanthanide-macrocycle binary complexes. Specifically, we compared the effectiveness of Sm, Eu, Tb, and Dy complexes with the macrocycle 1,4,7,10-tetraazacyclododecane-1,7-diacetate (DO2A) to the corresponding ...
