The magnesium-rich intermetallic phases RE3RuMg7 (RE = Y, Nd, Dy, Ho) have been synthesized from the elements in sealed niobium ampoules and subsequently characterized by powder X-ray diffraction. The structure of the dysprosium compound was refined on the basis of single-crystal X-ray diffractometer data: Ti6Sn5 type, P63/mmc, a = 1019.1(2), c = 606.76(9) pm, wR2 = 0.0159, 439 F2 values, 19 va...

We present (29)Si, (27)Al, and (67)Zn NMR evidence to show that silicate ions in alkaline solution form complexes with zinc(II) (present as zincate, Zn(OH)(3)(-) or Zn(OH)(4)(2-)) and, concomitantly, with aluminate (Al(OH)(4)(-)). Zincate reacts with monomeric silicate at pH 14-15 to form [(HO)O(2)Si-O-Zn(OH)(3)](4-) and with dimeric silicate to produce [HO-SiO(2)-O-SiO(2)-O-Zn(OH)(3)](6-). The...

The crystal structure of the title compound, [Ho(NO(3))(3)(C(15)H(15)NO(2))(2)]·H(2)O, contains two Schiff base 6-meth-oxy-2-[(4-methyl-phen-yl)iminiometh-yl]phenolate (L) ligands, three independent nitrate ions that chelate to the Ho(III) ion with O atoms and a hydrate water mol-ecule. The coordination environment of the Ho(III) ion is ten-coordinate. The L ligands chelate with a strong Ho-O(p...

The reaction of intracomplex proton transfer (44BPY(-.)...HO-H) (R)-->44BPYH(.)+ OH(-) that follows the photoreduction of 4,4'-bipyridine (44BPY) into its anion radical 44BPY(-) in the presence of 1,4-diazabicyclo[2.2.2]octane (DABCO) is investigated in acetonitrile-water mixtures by using picosecond transient absorption. The dependence of the appearance kinetics of the 44BPYH(.) radical on the...
