However, the variation of oxygen composition manifests itself as disorder in either the cation or anion sub-lattices, leading to a reduction in symmetry (to 2, 2or 2). In addition, three new structures have been identified at compositions closer to the perovskite ideal. One structure is ...
An X-ray crystallographic study of [{2,4,6-(CH3O)3C6H2}3PCN]I reveals an ionic structure with no long cation–anion interactions. In contrast, the crystal structure of [2,4,6-(CH3O)3C6H2]3PI2 represents a further ... SM Godfrey - 《Dalton Transactions》 被引量: 0发表: 1997年...

To synthesize LSMO nanoparticles with the general formula of ABO3, the A-site and B-site cation salts were separately dissolved, as in Fig. 1 (Step I) [33]. In this study, 0.002 mol of (Mn(NO3)2⋅H2O) was dissolved in 10 mL distilled water and stirred for 15 min, and 0.0014 ...

Regardless of the degree of solvation the cation and anion are apparently contact paired since the ions are formed in direct contact and it has been shown that, for analogous systems, M+NO3- ions are paired in direct contact. The magnitude of the v3(e) splitting ranges from 20 cm-1 for...
Supplementary Note 1 For our initial calculations the cyanamide cation seemed an ideal candidate for two reasons: its positive charge would complement the negative charge in 2 while leaving some electron density on N, and its C3v symmetry renders the computations more economical. As is summarized ...
c. 氮气和氨气并不是土壤中发现的氮的一种形式。在土壤中，氮主要以无机氮的形式存在，包括铵离子（NH4+）、硝酸盐（NO3-）和亚硝酸盐（NO2-）等。此外，还存在一定量的有机氮，如蛋白质、核酸、氨基酸等。氮气和氨气主要是在大气中存在，或者通过化学反应转化而来，而不是土壤中直接发现的氮的...
