The dehydrated copper silicate Na2[Cu2Si4O11]: a three-dimensional microporous framework with a linear Si—O—Si linkage
The structure of the title dehydrated copper silicate, disodium dicopper undeca-oxide tetra-silicate, Na(2)(Cu(2)O(11)Si(4)), was determined by single-crystal X-ray diffraction from a non-merohedral twin. It exhibits an effective three-dimensional microporous framework with the major channels, in which the Na(+) cations are placed, running along the a-axis direction and smaller channels observe...
متن کاملImpact of O-Si-O bond angle fluctuations on the Si-O bond-breakage rate
We extend the McPherson model for silicon-oxygen bond-breakage in a way to capture the impact of the O-Si-O angle fluctuations on the breakage rate. It is shown that the mean rate is more than 5 times higher and its standard deviation is comparable to the nominal rate corresponding to the fixed angle (typical for α-quartz). The mean rate has appeared to grow exponentially with the electric fiel...
متن کامل[O] [H] functionalization on carbon nanotube using (O2–H2) gas mixture DC glow discharge
The [O] [H] functionalization of carbon nanotube (CNT) was studied using oxygen–hydrogen (O2–H2) gas mixture direct current (DC) glow discharge plasma technique for cathode/CNT-anode separation of 0.10 ± 0.01 cm. O2 and H2 were fixed at flowrate of 10.0 ml/min in order to obtain gas mixture ratio of 1:1. During the (O2–H2) gas mixture DC glow discharge, current–voltage (I–V) characteristic of g...

In the title compound, [Ce(C(9)H(4)N(2)O(4))(C(2)H(3)O(2))(H(2)O)](n), the Ce(III) ion is coordinated by five O atoms and one N atom from four 1H-benzimidazole-5,6-dicarboxyl-ato (L) ligands and by two O atoms from an acetate ligand and one aqua ligand, forming a slightly distorted tricapped trigonal-prismatic geometry. The L ligands are bridging, forming a layered polymer parallel to (010). In...

In the title complex, [Pr(C(9)H(4)N(2)O(4))(C(2)H(3)O(2))(H(2)O)](n), the Pr(III) ion is coordinated by five O atoms and one N atom from four benzimidazole-5,6-dicarboxyl-ate ligands, two O atoms from an acetate ligand and one water mol-ecule, giving a tricapped trigonal-prismatic geometry. The benzimidazole-5,6-dicarboxyl-ate and acetate ligands connect the Pr(III) ions, forming a layer in the...
