摘要 标题化合物[(NH_4)(DB18C6)]_2[Ag(SCN)_2]_2其晶体属三斜晶系,空间群为P1。晶胞参数:a=14.003(2),b=14.461(3),c=14.887(2),a=66.51(2),β=66.70(1),γ=76.09(2)°,V=2527.13 3,M_r=1205.0,Z=2,D_x=1.58g/cm~3,μ=9.88cm^(-1)。偏差因子R_w=0.081,独立可观测点数[I>3σ(I)]为3351个,在配合物分子中,二苯并18-冠-6与NH4~+形成配阳离子,Ag~+与硫氰酸根形成配阴离子,二者以静电力形成配合物。银原子被两个SCN~-的S原子桥联和硫氰酸根上的硫,氮杂配,使整个分子形成一条高分子长链。 The crystal structure of the title complex belongs to the triclinic space group P1 with cell parameters:a= 14. 003(2),b=14. 461(3),c=35.092(6)A,a=66. 51(2),β=66. 70(1),γ=76. 09(2)°,Z=2,D_x= 1. 58 g/cm ̄3,V=2527. 1 A ̄3. R=0. 077 and R_w=0.081.The chemical formula of the crystal is [(NH_4 ) (DB18C6]_2[Ag (SCN )_2]_2.Its composition was determined by elemental analyses and X-ray structure analyses.The result of crystal structure analyses shows that in the crystal complex DB18C6 ccordinates with ammonium and silver(I) with thiocyanates.The [(NH_4) (DB18C6)] ion and [Ag_2(SCN)_4]  ̄(2-)ion are combined with by electronic force.
