利用间苯二乙酸、1,10-邻菲啰啉和高氯酸锰在水热条件下反应制备了一种新型超分子配合物{[Mn2(pda)(phen)4(H2O)2]·2H2O.2ClO4-}(H2pda=间苯二乙酸,phen=1,10-邻菲啰啉).通过X单晶衍射测定了晶体结构,并用元素分析、红外光谱等技术对其进行了表征.配合物属3斜晶系,空间群为P-1,a=1.129 0(2)nm,b=1.705 0(2)nm,c=1.734 5(1)nm;α=110.559(1)°,β=107.588(9)°,γ=93.102(12)°;Z=1,R1=0.071 0,wR2=0.202 9.晶体结构分析表明2个锰在1个间苯二己酸的连接下形成了一个双核结构,再在船型六元环氢键和π…π堆积共同作用下,双核结构单元被连成2维网络结构.毗邻的2维结构之间又通过氢键的支撑,拓展为3维网状超分子体系.
A novel supramolecular complex {[Mn2 (pda) (phen) 4 (H2O) 2] was prepared by the reaction of isophthalacetic acid, 1,10-phenanthroline and manganese perchlorate under hydrothermal conditions 2H2O.2ClO4 -} (H2pda = isophthalamic acid, phen = 1, 10-phenanthroline) .The crystal structure was determined by single crystal X-ray diffraction and characterized by elemental analysis and infrared spectroscopy. The genera 3 is orthorhombic with space group P-1, a = 1.129 0 (2) nm, b = 1.705 0 (2) nm, c = 1.734 5 (1) nm; = 107.588 (9) °, γ = 93.102 (12) °; Z = 1, R1 = 0.071 0, wR2 = 0.202 9. The crystal structure analysis shows that two manganese forms one under the connection of 1 isophthalic acid Dual-core structure, and then in the ship-type six-membered ring hydrogen bond and π ... π stacking together, the dual-core structural unit is connected into a two-dimensional network structure .Adjacent two-dimensional structure through the hydrogen bond between the support, extended to three-dimensional network Supramolecular system.
