Infrared and Raman spectra of two solvatomorphs of a new dimethylammonium polytungstate decakis(dimethylammonium) dihydrogendodecatungstate, (Me₂NH₂)(H₂W₁₂O₄₂)·nH₂O (n = 10 or 11), were evaluated and discussed. The assignment of bands corresponding to the cationic and anionic components as well as the water of crystallization is presented. Deuteration has been used in the interpretation of the spectra. The dimethylammonium cation and the molecules of water of crystallization form a network of regular and multifurcated hydrogen bonds, thus a fraction of the N–H hydrogen atoms are so strongly bound to the anion, that the compound can only be deuterated with an aggressive procedure. The method for deuteration is described in detail. The deuterated undecahydrate can be obtained from both solvatomorphs.

仲钨酸二甲铵B水合物的氘代和振动光谱

新型二甲基铵多钨酸盐癸基（二甲基铵）二氢十二碳酸盐，（Me ₂ NH ₂）（H ₂ W ₁₂ O ₄₂）· n H ₂ O（n= 10或11），进行了评估和讨论。给出了对应于阳离子和阴离子组分以及结晶水的带的分配。氘化已用于解释光谱。二甲基铵阳离子和结晶水分子形成规则的和叉状的氢键网络，因此，一部分N–H氢原子与阴离子紧密结合，因此该化合物只能通过强力的程序进行氘化。详细描述了氘化方法。氘化的十一水合物可以从两种溶剂化物中获得。
