A novel silver-containing compound, bis(benzylamino)silver(I) benzylcarbamate, with an unusual molecular structure is easily synthesized by the reaction of benzylammonium benzylcarbamate and silver oxide. It crystallizes in the triclinic crystal system with the space group P ̅1 with a = 5.2006 (5), b = 14.6298 (15), c = 14.7246 (15) Å, α = 68.729 (2), β = 83.507 (2), γ = 85.412 (2)° and Z = 2. In the crystal, one Ag atom coordinates with the two amino groups in two benzylamine molecules, and there are no silver-silver and silver-oxygen interactions. The carboxylate groups take part in balancing the electric charge and forming hydrogen bonds. Both the compound and the starting material benzylammonium benzylcarbamate exhibit room-temperature solid-state emissions with the peaks at 300 and 406 nm, respectively.
一种具有独特分子结构的新型含银化合物，苄基氨基甲酸双（苄基氨基）银（I），可通过苄基氨基甲酸苄铵与氧化银反应轻松合成。它在三斜晶系中结晶，空间群为P ̅1，a = 5.2006（5），b = 14.6298（15），c = 14.7246（15）Å，α = 68.729（2），β = 83.507（2），γ = 85.412（2）°，Z = 2。在晶体中，一个Ag原子与两个苄胺分子中的两个氨基配位，不存在银-银和银-氧相互作用。羧酸根基团参与电荷平衡并形成氢键。该化合物和起始原料苄基氨基甲酸苄铵在室温下均表现出固态发射，峰值分别位于300和406 nm处。
