广西自1958年成立自治区以来,便称为广西壮族自治区,或简写为广西、广西区,可是至今你们仍把广西壮族自治区叫做广西省加入文内或标题中。我的原文中不曾使用“广西省”这一称呼。我为了省便,在文中把广西壮族自治区简称为广西。这种写法没有毛病。可是你们把“省”字加进去,就不大合适了。因此,请你们更正。另外,36页第一行改后的含义与原义相反了。“形成泥炭有机残体来自山坡或河流…”。原文是指异地堆积型尼

Zemannite-type Selenites: Crystal structures of K2[CO2(SeO3)3] · 2H2O and K2[Ni2(SeO3)3] · 2H2O

Summary Crystals of K₂[Co₂(SeO₃)₃]-2H₂O and K₂[Ni₂(SeO₃)₃]-2H₂O were synthesized under low-hydrothermal conditions. Their structures were determined using single crystal X-ray data up to sin / = 0.7Å^-1. [Space group P6₃/m; a = 9.091(3),9.016(2)Å; c = 7.562(2), 7.476(2)Å; Z = 2; R_W = 1.6, 2.5%]. The investigations confirmed that K₂[Co₂(SeO₃)₃].2H₂O and K₂[Ni₂(SeO₃)₃]-2H₂O represent the first selenites belonging to the zemannite structure type, a framework structure with wide channels running parallel [0001]. In both compounds four maxima were clearly located in the channel by Fourier summations and attributed to two K atoms and two H₂O molecules, each with an occupancy factor of 1/6; a possible ordering scheme (full occupancy) with local symmetry 1 and [6]-coordinated K atoms could be derived for the channel atoms.Zusammenfassung Kristalle von K₂[Co₂(SeO₃)₃]-2H₂O und K₂[Ni₂(SeO₃)₃]-2H₂O wurden unter niedrig-hydrothermalen Bedingungen synthetisiert. Die Strukturen wurden unter Verwendung von Einkristallröntgendaten bis sin /= 0.7Å^-1 bestimmt. [Raumgruppe P6₃/m; a = 9.091(3), 9.016(2)Å; c = 7.562(2), 7.476(2)Å; Z = 2; R_W = 1.6, 2.5%] Die Untersuchungen bestätigten, daß K2[Co₂(SeO₃)₃] - 2H₂O und K₂ [Ni₂(SeO₃)₃] - 2H₂O als erste Selenite dem Strukturtyp des Zemannits angehören, einer Gerüststruktur mit weiten, parallel [0001] verlaufenden Kanälen. In beiden Verbindungen wurden im Kanal vier Maxima durch Fourier-Summationen eindeutig lokalisiert und zwei Kalium-atomen sowie zwei H₂O Molekülen, jeweils mit einem Besetzungsfaktor von 1/6, zugeschrieben. Für die Kanalatome konnte ein möglicher Ordnungszustand (volle Besetzung) mit lokaler Symmetrie 1 und [6]-koordinierten Kaliumatomen abgeleitet werden.

A study on the effects of drying conditions on the stability of NaNd(CO3)2·6H2O and NaEu(CO3)2·6H2O

The effect of different drying conditions on the stability of NaNd(CO₃)·6H₂O and NaEu(CO₃)·6H₂O and the identity of the decomposition product have been investigated. The rate of decomposition and the nature of the altered phases are dependant on the drying conditions used. When the phases are oven dried at 120 °C, the decomposition is immediate and the phase completely alters to Nd₂(CO₃)₃ or Eu₂(CO₃)₃ respectively. Under less severe drying conditions, the Na rare earth carbonate phases alter to Nd₂(CO₃)₃·8H₂O and Eu₂(CO₃)₃·8H₂O over a period of 24–48 h, but they can be kept indefinitely in a water saturated environment. The implications for using Nd and Eu as actinide analogues are discussed.
