本文报道K(C_(12)H_(24)O_6)Ag(SCN)_2(Ⅰ)、Na(CI_(12)H_(24)O_6)Ag(SCN)_2(Ⅱ)及NH_4(C_(12)H_(24)O_6)Ag(SCN)_2(Ⅲ)的单晶合成、晶体学常数以及化合物(Ⅰ)的晶体结构测定结果,化合物(Ⅰ)属正交晶系,空间群为F_(?dd)(NO.43,非标准取向),a=8.833(2)b=27.926(2),c=35.508(6)(?),V=8 (?),Z=16,D_(obs)=1.62,D_c=1.65gcm~(-3),μ=13.3cm~(-1).化合物(Ⅰ)晶体中,Ag原子以3.562和5.271(?)两种距离交替排列于晶体学二重轴上,SCN~-则分别以单齿(S原子)和双齿(S原子和N原子)与相邻Ag原子交替形成(?)桥(?)“SCN”桥,因而构成无限的Ag_(2x)(SCN)_(4x)~x~(1/2)长链;K~+离子以离子一偶极力位于冠醚环中心,形成[K(Cl_(12)H_(24)o_6)]~+离子,后者通过K~+离子以静电力与Ag_(2x)(SCN)_(4x)~x~(1/2)链上SCN~-的N相结合.
In this paper, the effects of Ag (SCN) _2 (I), Na (CI_ (12) H_ (24) O_6) Ag (SCN) _2 (Ⅱ) and NH_4 (C_ (12) (Ⅰ) belongs to the orthorhombic system, the space group is F _ (? Dd), and the crystal structure of the compound (I) A = 8.833 (2) b = 27.926 (2), c = 35.508 (6) ?, V = 8 ?, Z = 16, D obs = 1.62, D_c = 1.65gcm -3 and μ = 13.3cm -1. In the crystal of compound (I), the Ag atoms are alternately arranged on the double axis of crystallinity at 3.562 and 5.271 (? (SCN) bridges with adjacent Ag atoms by single tooth (S atom) and bidentate (S atom and N atom), respectively, thus forming an infinite Ag 2 × (2 ×) (SCN) _ (4x) ~ x ~ (1/2) long chain; K ~ + ions are located at the center of the crown ether ring with a dipole force of ions and form [K (Cl 12 H 24 O 6) Ions which are electrostatically combined with N of SCN ~ - on the Ag_ (2x) (SCN) _ (4x) ~ x ~ (1/2) chains by K ~ + ions.
