The mononuclear title compound, [Ti(C(5)H(10)NO(2))(4)], is a rare example of an eight-coordinate Ti(IV) compound in which all donor atoms are O atoms. The coordination geometry around Ti(IV) is pseudo-dodeca-hedral and...

In the centrosymmetric title compound [Ti(2)Cl(6)(C(6)H(13)N(2))(2)(C(6)H(14)N(2))(2)]·2C(2)H(3)N, an inversion center relates the two Ti atoms which display a distorted octa-hedral coordination geometry. There are two uncoordinated acetonitrile solvent mol-ecules per mol-ecule...

Two new carbamatomagnesium bromide complexes 1 (=[Mg(O2CN(Me)Ph)(THF)2Br]2) and 2 (=[Mg3(O2CNPh2)4(THF)5Br][(THF)MgBr3]) were prepared and crystallographically characterized. Complex 1 consists of a dinuclear core with two syn-syn-mu(1,3) bridging carbamato ligands. In solution,...

The tetranuclear basic zinc carbamates Zn4O(O2CAm)6(1, Am =N-diethylamino; 2, Am =N-piperidyl; 3, Am =N-pyrrolidyl) were shown by transient FTIR spectroscopy to undergo C-N bond metathesis reactions that result in exchange...

The interaction of a series of phosphate diesters and triesters (1=diphenyl phosphate,2=dimethyl phosphate,3=bis(2-ethylhexyl) phosphate,4=trimethyl phosphate,5=methyldiphenyl phosphate,6=triphenyl phosphate) with [Mg(15-crown-5)](2+) (15-crown-5=1,4,7,10,13-pentaoxocyclopentadecane) was studied as a simplified model for the interaction of...

Three bis(N-alkyldithiocarbamato)cadmium(II) complexes [Cd(S(2)CNHR)(2)] (1, R = n-C(3)H(7); 2, R = n-C(5)H(11); 3, n-C(12)H(25)) were prepared by metathesis of the corresponding lithium salt, Li[S(2)CNHR], with cadmium chloride. The crystal structures...

The reaction between Mn(6)L(12) and Mg(6)L(12) (L = N,N-diethylcarbamate) results in isolation of heteronuclear complexes Mn(n)Mg(6)(-)(n)L(12). A series was prepared with different doping factors n by varying the Mn/Mg ratio...

Binuclear manganese complexes Mn2(III/IV)(dtsalpn)2DCBI, 1, Mn2(III/III)(dtsalpn)2HDCBI, 2, containing the ligand dicarboxyimidazole (DCBI) have been prepared in order to address the issue of imidazole bridged and ferromagnetically coupled Mn sites in...

The N-carboxyimidazolidone anion, 2(-), was prepared as an analogue for N(1)-carboxybiotin, and the kinetics of its CO(2)-dependent chemistry were studied in polar aprotic media. The objective was to assess the...

Heteronuclear diethylcarbamato complexes of the form Co(n)()Mg(6)(-)(n)()(Et(2)NCO(2))(12) were prepared from the isostructural homonuclear precursors Mg(6)(Et(2)NCO(2))(12), 1, and Co(6)(Et(2)NCO(2))(12), 2, via a solvothermal methodology. Two materials were selected for single-crystal X-ray...
