  er complex
These results suggested that the estrogen receptor (ER) complex might alter histone acetylation as part of the gene activation process.
      
However, corresponding exposure in normal orientation leads to subsequent disintegration of the distal ER complex, loss of amyloplast starch, confluence of lipid droplets, and an increase of the lytic compartment.
      
These ultrastructural events thus appear to be induced by a physical contact - however short - between amyloplasts and the distal ER complex.
      
Sedimentation of amyloplasts and nucleus to the centrifugal (distal) cell pole and the lateral displacement of the distal endoplasmic reticulum (ER) complex occur after centrifugation for 20 min at an acceleration of 50 g.
      
Within the first 7.5 min, after the roots have been returned to 1 g, the original arrangement of the amyloplasts sedimented on the underlying ER complex is reestablished in 66% of the statocytes.

In this paper, fourteen new solid complexes of rare earth with 1,6-bis-(1'-phenyl-3'-methyl-5' -pyrazolone-4')-1 ,6-hexanedione (BPMPHD, H2L) and a,a-dipyridyl(DPy, D) have been synthesized and characterized. The stoi-chiometry of the complexes was confirmed by elemental analysis, R2L3D2.nH2O (R=La,Y5 w = 10;R=Sm, ...,Lu5 n=4), R2L3D.4H2O(R=Pr, Nd). Determinations and discussions have been made for the 1R, UV-visible spectra,fluorescence spectra and DTA-TG spectra of these complexes. The decomposition temperature...

In this paper, fourteen new solid complexes of rare earth with 1,6-bis-(1'-phenyl-3'-methyl-5' -pyrazolone-4')-1 ,6-hexanedione (BPMPHD, H2L) and a,a-dipyridyl(DPy, D) have been synthesized and characterized. The stoi-chiometry of the complexes was confirmed by elemental analysis, R2L3D2.nH2O (R=La,Y5 w = 10;R=Sm, ...,Lu5 n=4), R2L3D.4H2O(R=Pr, Nd). Determinations and discussions have been made for the 1R, UV-visible spectra,fluorescence spectra and DTA-TG spectra of these complexes. The decomposition temperature of the coordination compounds has the "tetra effect" and "double peaks". The hypersensitive transition of Nd, Ho, Er complexes and the fluorescence of the Sm, Eu, Tb, Dy, Tm and La, Lu, Y, Gd complexes have been attributed. The flourescence quantum yield of Tb complex was measured also.

The title complexes [Ln (Gly)2. 4H2O].Cl 3. nH2O (Ln=Gd,Er,Yb) were synthesized in aqueous solution. The iR spectra of the complexes were measured and the principal IR bands were assigned. The result showed that glycine molecules are zwitterions in the complexes and coordinate to rare earth ions through carboxyl groups. Each rare earth ion is coordinated by four water molecules. There is also an uncoordinated water molecule in Gd and Er complex. The structures of the complexes have been proposed.The Yb complex has the symmetric structure of one dimensional chain of infinite length and the other two complexes have the unsymmetric structure of one dimensional chain of infinite length.

在水溶液中制备了配合物[Ln(Gly)2·4H2O]·Cl3·nH2O(Ln=G、Er、Yb),测定了配合物的红外光谱,并对其主要红外吸收带进行了归属。结果表明,甘氨酸以内盐的形式存在于配合物中,并通过羧基与稀土离子配位。四个水分子参与了配位,在Gd和Er的配合物中还有一个水分子未参与配位。推测Yb配合物为对称的一维无限长链结构,其余两种配合物为不对称的一维无限长链。

Tricyclopentadienyl cerium tetrahydrofuranate (THF) was prepared by the reaction of (NH4)2Ce(NO3)6 with sodium cyclopentadienide(C5H5Na)in THF at molar ratio of 1:6 to give a brown crystal of (η5-C5H5)3Ce·OC4H8; tricyclopentadienyl erbium tetrahydrofuranate complex was synthesized by the reaction of ErCl3·nTHF with potassium cyclooctadienide (C8H11K) at molar ratio of 1:1 at - 78℃, and tnen C5H5Na in THF (at molar ratio of ErCl3·nTHF to C5H5Na 1:2)was added to the above solution at room temperature to give the...

Tricyclopentadienyl cerium tetrahydrofuranate (THF) was prepared by the reaction of (NH4)2Ce(NO3)6 with sodium cyclopentadienide(C5H5Na)in THF at molar ratio of 1:6 to give a brown crystal of (η5-C5H5)3Ce·OC4H8; tricyclopentadienyl erbium tetrahydrofuranate complex was synthesized by the reaction of ErCl3·nTHF with potassium cyclooctadienide (C8H11K) at molar ratio of 1:1 at - 78℃, and tnen C5H5Na in THF (at molar ratio of ErCl3·nTHF to C5H5Na 1:2)was added to the above solution at room temperature to give the pink crystal of (η5-C5H5)3Er·OC4H8. The crystal structure determination of both complexes showed that both crystals belong to monoclinic space group P21/n. The Oe complex structure is different from those of (η5-C5H5)8Ln·OC4H8(Ln = La, Pr, Nd, Gd, Dy, Y, Lu). They are not isostructural, but the Er complex is isostructural with them. The distance Oe-O, av. Ce-C(η5) and Ce-Cent (Centroid of cyclopentadienyls) are not consistent with the lanthanide contraction regularity, but those of Er-O, av. Er-C(η5) and Er-Cent are consistent with it.It means that there are two discontinuity points at Oe and Dy but no "gadolinium break phenomenon" is observed in the isostructural series of (η5-C5H5)3Ln·OC4H8 because the bond lengths of Ln-O and Ln-C(η5) and the Ln-centroid distance of the elements (Y, Er, Lu) are not greater than those of Gd.

用无水硝酸铈铵[(NH_4)_2Ce(NO_3)_6]与环戊二烯钠(C_5H_5Na)在四氢呋喃中按1:6摩尔比反应,得到(η~5-C_6H_5)_3Ce·OC_4H_8;用ErCl_3·nTHF与环辛二烯钾(C_8H_(11)K)按等摩尔比于-78℃反应,升至室温,再按1:2摩尔比加入C_5H_5Na,得到了(η~5-C_5H_5)_3Er·OC_4H_8.两配合物晶体结构测定结果表明都属单斜晶系P2_(1/n)空间群.Ce配合物与已测定过的(η~5-C_5H_5)_3Ln·OC_4H_8(Ln=La,PrNd,Gd,Dy,Y,Lu)的晶体结构不是同构物:而Er配合物则是同构物.Ce配合物中的Ce—O、Ce—Cent(环戊二烯环中心)和平均Ce—C(η~5)键长不符合镧系收缩规律,而Er配合物的键长符合.这说明在(η~5-C_5H_5)_3Ln·OC_4H_8同构系列中在Ce和Dy有两个断点,但不存在所谓的“钆断现象”,因为Y,Er,Lu配合物的Ln—O和Ln—C(η~5)和Ln—Centroid距离不大于Gd的相应值.
