	abstract = {Vanadium compounds, in vitro, stimulate glucose uptake and inhibit lipid breakdown, in a manner remarkably reminiscent of insulin{\textquoteright}s effects. In vivo, vanadium enhances insulin{\textquoteright}s plasma glucose and lipid-lowering properties, leading to normalization of diabetic symptoms in the presence of only minimal endogenous insulin. The coordination chemistry of vanadium has great versatility for adjustment of pharmacological characteristics. Vanadium compounds are generally also very redox active, which is both advantageous and detrimental for optimizing biochemical function. In this perspective, we review and comment on how these properties have been revealed, what questions have arisen along the way, and where future investigations may be headed. While this is not a comprehensive overview of all available compounds touted as {\textquoteright}insulin enhancing agents{\textquoteright}, it will focus on those which are distinctive in some way, or which are representative of the larger library of vanadium compounds, including all currently known relevant oxidation states of vanadium.},

The formation constants of the Lu (log beta(1) = 1.79, log beta(2) = 4.40) and the Yb (log beta(1) = 2.25, log beta(2) = 4.42) complexes were determined at pH = 1.5 using an unusual P-31 NMR spectroscopic method. The molecular structure of the lutetium complex [Lu(H(3)ppma)(2)](NO3)(3) . 3H(2)O (C60H96LuN11O24P6) was solved by X-ray methods; it crystallizes in the trigonal space group R(3) over barc$, with a = 19.060(1) Angstrom},

	abstract = {A new water-soluble N4O3 tripodal amine phenol ligand, tris(((2-hydroxy-5-sulfobenzyl)amino)ethyl)amine (H(3)TRNS) has been synthesized, and its complexation properties with six lanthanide(III) ions (Ln, Nd, Gd, Ho, Yb, Lu) have been probed. In water, the ligand coordinates in a tridentate fashion through the three phenolate oxygen atoms to give mono- and bis(ligand) complexes. The bis complexes are proposed to be 7-coordinate containing one bound water as evinced by O-17 NMR experiments on the Dy3+ complex. while the mono complexes are proposed to have a coordination number of eight or nine. The stepwise formation constants for the 1:1 and 2:1 (L:M) complexes have been measured at 25 degrees C (mu = 0.16 M NaCl) for Nd3+ (log K-1 = 6.41, log K-2 6.34), Gd3+ (log K-1 = 6.67, log K-2 = 7.69), Ho3+ (log K-1 = 7.67, log K-2 = 8.75), and Yb3+ (log K-1 = 8.53, log K-2 = 9.73). The formation constants show an increasing affinity and an unprecedented selectivity for the heavier lanthanides (beta(2(yb)) - beta(2(Nd)) = 10(5.5)). Furthermore, the stepwise stability constant for the 2:1 complex is increasingly greater than that for the 1:1 complexes of Gd3+, Ho3+, and Yb3+, while K-1 and K-2 for the 1:1 and 2:1 complexes of Nd3+ are approximately the same. Solution calorimetry shows that the selectivity for the heavier lanthanides is an enthalpic effect (Delta H-beta 2 = -45.11 (Yb) and -13.71 kJ . mol(-1) (Nd)), while the anomalous behavior in formation constants (K-2 > K-1) is predominantly entropic (Delta S-2 > Delta S-1) and is rationalized in terms of salvation of the complexes, Lanthanum(III) forms only the 1:1 complex (log K = 5.65) which precipitates from solution.},
