利用柔性配体(4,4’-二苯醚二甲酸,4,4’-oxyd ibenzoic acid,H2oba)与Zn(NO3)2反应得到了一种新型有机晶体C14H10O5,通过元素分析、X-射线单晶衍射等技术测定了晶体结构,结果表明,配合物属单斜晶系,空间群P21/c,a=5.7204(14)A°,b=27.473(7)A°,c=14.821(4)A,°β=90°;Z=8;R=0.0555。在有机晶体中,紧邻分子单元通过氢键作用在b轴形成一维链;链间籍氢键相互作用拓展为三维超分子网络。
A novel organic crystal, C14H10O5, was obtained by the reaction of 4,4’-oxydibenzoic acid (H2oba) with Zn (NO3) 2. The results of X-ray diffraction The results show that the complex belongs to the monoclinic system with space group P21 / c, a = 5.7204 (14) A °, b = 27.473 (7) A ° and c = 14.821 (4) ) A, ° β = 90 °; Z = 8; R = 0.0555. In organic crystals, adjacent molecular units form a one-dimensional chain in the b-axis through hydrogen bonding; hydrogen bonding interactions among chains expand into three-dimensional supramolecular networks.
