A series of lanthanide complexes [LnClx(bpy)y(H2O)z]Cl3-x(H2O)n(EtOH)m (Ln ) Eu, Gd, Tb; x ) 1, 2; y ) 1, 2; z ) 2-4) with different numbers of 2,2′-bipyridine (bpy), chloride ions, and water molecules in the inner coordination sphere were synthesized and ...
Upon reacting P4S3 with AgAl(hfip)4 and AgAl(pftb)4 [hfip = OC(H)(CF3)2; pftb = OC(CF3)3], the compds. Ag(P4S3)Al(hfip)4 (1) and Ag(P4S3)2+[Al(pftb)4]- (2) formed in CS2 or CS2/CH2Cl2 soln., resp. Compds. 1 and 2 were characterized by single-crystal x-ray ...
Electron-spin relaxation is one of the determining factors in the efficacy of MRI contrast agents. Of all the parameters involved in determining relaxivity it remains the least well understood, particularly as it relates to the structure of the complex. On ...
The synthesis and characterization of a series of cobalt(III) complexes of the general type Co(N2O2)(L-2) are described. The N2O2 Schiff base ligands used are Me-salpn (H2Me-salpn = N,N'-bis(methylsalicylidene)-1,3-propylenediamine) (1-3) and Me-salbn ...
Mononuclear trivalent lanthanide complexes with formula [Ln(L)(NO3)3] [in which L=4,4-difluoro-8-(2:2;6:2-terpyridin-4-yl)-1,3,5,7-tetramethyl-2,6-diethyl-4-bora-3a,4a-diaza-s-indacene (Boditerpy)] are reported for Ln=Yb, Nd, Er, La and Gd. According to th ...
The incommensurate palmierite-like structure of beta-K5Yb(MoO4)(4), potassium ytterbium tetramolydate, has been refined in the (3 + 1)- dimensional monoclinic superspace group X2/m(0 rho 0) 00, with X = [0 0 0 0; 1/2 1/2 0 0; 0 0 1/2 1/2; 1/2 1/2 1/2 1/2] ...
Metal ions are constituents of many metalloproteins, in which they have either catalytic (metalloenzymes) or structural functions. In this work, the characteristics of various metals were studied (Cu, Zn, Mg, Mn, Fe, Co, Ni, Cd and Ca in proteins with know ...
D. functional (DFT) studies and hybrid QM/MM-DFT calcns. demonstrate the importance of p-p stacking interactions in detg. the structural features of two exemplary d8 palladium complexes, PdBr(p-NCC6H4)({S}-MeO-Biphep), 1, and PdBr(C6F5)({S}-MeO-Biphep), 2. ...
A DTPA-based chelate containing one phosphinate group was conjugated to a generation 5 polyamidoamine (PAMAM) dendrimer via a benzylthiourea linkage. The Gd(III) complex of this novel conjugate has potential as a contrast agent for magnetic resonance imagi ...
