摘　　要：室温下将 [NEt4 ]3[Fe (CN) 6 ]和 [Mn (salophen) (H2 O) (CH3OH ) ]ClO4 反应 ,得到了超分子化合物[NEt4 ][Mn(salophen) (H2 O) 2 ]2 [Fe(CN) 6 ]·H2 O·CH3OH (salophenH2 =双水杨醛缩邻苯二胺 ) ,并对其进行了晶体结构测定 .结果表明 ,该晶体属三斜晶系 ,空间群P1- ,晶胞参数a =1.2 15 0 ( 4)nm ,b =1.483 4( 6)nm ,c =1.662 5 ( 6)nm ,α =81.896( 7)° ,β =76.980 ( 8)° ,γ =81.12 0 ( 6)°,V =2 .872 ( 2 )nm3,Z =2 ,Dc=1.3 88g·cm-3.The supramolecular compound [Mn(salophen)(H_2O)_2]_2·H_2O·CH_3OH [salophenH_2=N,N′-bis(salicylidene)-1,2-diaminobenzene] was synthesized by reacting _3- with [Mn(salophen)(CH_3OH)(H_2O)]ClO_4 at room temperature. Its structure was determined by X-ray analysis. The crystal belongs to triclinic system, space group P1-, with unit cell dimensions a= 1.2150(4) nm, b=1.4834(6) nm, c=1.6625(6) nm, α=81.896(7)°, β=76.980(8)°, γ=81.120(6)°, V= 2.872(2) nm 3, Z=2, D_c=1.388 g·cm -3. The network structure of the supramolecule is attributed to the hydrogen bonding in the compound. The results of thermal analysis, IR, UV-vis can also be explained by the structure data.
