摘要
通过固态偏合成反应合成了新型二元金属碳二亚胺 La2S2(CN2)。根据单晶 X 射线衍射数据解析并完善了晶体结构，其空间群为 C2/m。晶体结构表现为层状结构，由镧、硫化物和碳化二亚胺单元交替组成。本文讨论了该结构与 La2O2C2 结构的相似性，以及镧原子较少见的配位数 7。
The new binary metal carbodiimide La2S2(CN2) was synthesized via solid‐state metathesis reaction. The crystal structure was solved and refined on basis of single‐crystal X‐ray diffraction data with space group C2/m. The structure is represented by a layered structure, based on alternating layers of lanthanum, sulfide, and carbodiimide units. A close resemblance of the structure with that of La2O2C2 is discussed, as well as the less‐common coordination number seven of the lanthanum atom.
