The tripodal H(3)thqtcn ligand allows the synthesis of well-defined neutral monomeric syn-tris(hydroxyquinolinate) complexes of lanthanides. Pure [Ln(thqtcn)] complexes (Ln = Nd, 1; Er, 2; Yb, 3) of the triply deprotonated ligand thqtcn(3-) were prepared. Crystallographic characterization was carried out for

A novel dicyanoosmium(III) complex, trans-Ph(4)P[Os(III)(salen)(CN)(2)].CH(2)Cl(2).H(2)O (1; Ph(4)P(+) = tetraphenylphosphonium cation, salen(2-) = N,N'-ethylenebis(salicylideneaminato) dianion), has been synthesized and structurally characterized. Reactions of 1 with [Cu(Me(3)tacn)(H(2)O)(2)](ClO(4))(2) (Me(3)tacn = 1,4,7-trimethyl-1,4,7-triazacyclononane) under different conditions produce the 1-D ferromagnetic zigzag chains [Os(salen)(CN)(2)](2)[Cu(Me(3)tacn)].CH(3)OH (2) and

Construction of enzyme-like artificial cavities is a complex and challenging subject. Rather than synthesizing complicated host molecules, we have proposed mechanical adaptation of relatively simple hosts within dynamic media to determine the optimum conformation for molecular recognition. Here we have

Commercial gadolinium magnetic resonance imaging (MRI) contrast agents are limited by low relaxivity (r₁) and coordination to only a single water molecule (q = 1). Consequently, gram quantities of these agents must be injected to obtain sufficient diagnostic contrast. In this study
