In organic chemistry, the phenyl group, or phenyl ring, is a cyclic group of atoms with the formula C6H5, and is often represented by the symbol Ph (archaically φ) or Ø. The phenyl group is closely related to benzene and can be viewed as a benzene ring, minus a hydrogen, which may be replaced by some other element or compound to serve as a ...

四苯硼钾别名：四苯硼化钾，四苯硼酸钾，是一种难溶于水的钾盐。 化学式KB (C6H5)4。 主要用于 分析试剂。 物性：白色结晶。 溶于丙酮，不溶于水。 四苯硼钾是少有的不溶钾盐，这也造就了可溶的四苯硼酸盐的用途。 在中性、碱性或HAc性溶液中，四苯硼钠会与钾离子定量反应，生成难溶于水的白色沉淀四苯硼钾，可用于鉴定钾离子。 六硝基合钴酸钠钾 (K2Na [Co (NO2)6])，黄色沉淀，现象更明显，但是可溶六硝基合钴酸盐（如 六硝基钴酸钠）对酸碱更不稳定。 氯铂酸钾 …

In C (C6H5)4 it is possible to locate only the center of gravity of bands 2 and 3 (see Table I). In interpreting the spectrum, band 1 is taken as the origin of the first electronic transition in these molecules. It represents the transition between the vibrationless ground state and the vibrationless excited state.

首先，计算 C(C 6 H 5) 4 中每个原子的数量： C: 25, H: 20. 然后，查找元素周期表中每个元素的原子量： C: 12.0107, H: 1.00794 现在，计算原子数与原子量的乘积之和： 摩尔质量 (C(C 6 H 5) 4) = ∑ Count i * Weight i = Count(C) * Weight(C) + Count(H) * Weight(H) = 25 * 12.0107 + 20 * 1.00794 = 320. ...

2015年8月5日 · However, few organic systems studied to date have negative Re(γ) in the long wavelength limit, and all inorganic materials show positive nonlinear refraction in this limit. Here, we introduce a new class of molecules of the form X(C6H5)4, where X = B(-), C, N(+), and P(+), that have negative Re(γ).

R obertson 和 Woodward 在他们对托烷 C6H-C 结构的研究中首次通过 X 射线分析确定了三键的长度。 C—CSH53)。 他们表明，三键对相邻“单”键的长度有很大影响。 了解两个三键对相邻单键的影响以及相邻单键对三键长度的影响似乎很有趣。 含有两个共轭三键的化合物，由于其挥发性小且晶体发达，适合于 X 射线分析的是二苯基二乙炔。 首先将详细讨论 X 射线分析，然后将讨论结果。 已通过 X 射线分析研究了 1.4 diphenylbutadiïne 1.3（二苯基二乙炔）的晶体结构。 空间 …

The molecular and crystal structures of C(C6H5)4, Si(C6H5)4, Sn(C6Hs)4 and Pb(C6Hs)4 have been determined by conformational analyses and lattice energy calculations.
