The Interligand Aromatic Ring Stacking Interactions in the Mixed Complex（Ⅰ）──Synthesis, Crystal and IR Spectrum of Complex [Cu(C10H8O4) (C10H8N2) （H2O）]·2H2O
【摘要】 合成了Cu（bipy）[BMA]·3H2O混配配合物单晶（BMAH2为苄基丙二酸），测定了其晶体结构.该晶体属于正交晶系，空间群为Pbca，晶胞参数：α=1．6593（3）nm，b=1．4673nm，c=1．6747（3）nm，Z=8．R和Rw分别为0．037和0．038．晶体结构表明分子间芳环堆砌作用和分子间氢键作用是此晶体形成的主要作用力．晶胞中的分子间芳环堆砌作用不同于已往的文献报道，具有分子识别的特点．
【Abstract】 The mixed complex Cu (bipy) [BMA]·3H2O (where BMAH, stands for benzylmalonic acid) was synthesized and its crystal structure was determined. The crystal belongs to orthorhombic system and space group Pbca with parameters: α=1.659 3 (3) nm, b= 1. 467 3(3) nm, c=1.674 7(3) nm, V=4. 077(2) nm3, Z=8, Dc=1. 52 g/cm3. Final R and Rw are 0. 037 and 0. 038 respectively. The crystal structure shows that the major forces of crystal formation come from the intermolecular aromatic stacking and hydrogen bonding.This intermolecular stacking interaction in the crystal differs from that in other reports.Molecule recognition interaction is found in the crystals.
