The structure of the title compound, N,N,N′,N′-tetramethylethylenediammonium dichromate monohydrate, (C6H18N2)[Cr2O7].H2O, can be described as an alternate stacking of inorganic and organic layers parallel to the (010) plane. Structural cohesion is established by a three-dimensional network...
CH2=0 中 0有孤对电子.会和CH3NH2中的H形成氢键.CH3NH2中 N电负性较大.外存 -NH2 N也会和CH2=0中的H和自己当中的H原子形成氢键.因为N有孤对电子 H30+,NH4+ ,H20,NH3,都会存在氢键.因为0 N的电负性较大,吸电子能力强,半径又小,加上含F等化合物可以成氢键.B(OH)3也可以.不过只有B(0H)3其他的...
