A mononuclear manganese complex [Mn(2,2′-bipy)(H2O)4]·(m-phth) (2,2′-bipy=2,2′-bipyridine, m-phth=isophthalate) has been synthesized by hydrothermal methods. The crystal structure was determined by single-crystal X-ray diffraction. The crystal is of orthorhombic, space group Pnna with a=0.766 8(8) nm, b=2.050 2(2) nm, c=1.247 0(13) nm, V=1.960 4(4) nm3, Z=4, Mr=447.30, Dc=1.376 g·cm-3, μ=0.722 mm-1, F(000)=924, Rint=0.027 0, R=0.028 0 and wR=0.075 5. In the crystal the manganese atom is six-coordinated by two nitrogen atoms from 2,2′-bipyradine and four oxygen atoms from water molecules, completing an octahedral coordination geometry. The isophthalate molecules are included in the lattice and connected to Mn(2,2′-bipy)(H2O)4 by hydrogen bonding interactions to form a three-dimensional supramolecular structure.

A coordination polymer of {[Co(2-OPA)2(4,4′-bipy)(H2O)2]·6H2O}n (2-OPA-=2-oxo-1(4H)-pyridineacetate anion) was synthesized and characterized by elemental analysis, IR, TG, fluorescence and X-ray single crystal diffraction. The title complex crystallizes in triclinic space group P1, with a=0.856 66(17) nm, b=0.859 58(17) nm, c=1.142 2(2) nm, α=69.64(3)°, β=68.35(3)°, γ=74.88(3)°, and V=0.724 4(3) nm3, Z=1, R=0.064 4, wR=0.159 8. Each Co atom occupies a special position of inversion center and has an octahedral coordination environment, defined by two carboxyl O atoms from two 2-OPA- ligands, two N atoms from two 4,4′-bipy ligands and two water molecules. Adjacent Co(Ⅱ) atoms are bridged by 4,4′-bipy ligands, forming a one-dimensional linetype chain structure. The closest Co…Co distance is 1.142 2(2) nm. The results of TG and fluorescent analysis show that the title coordination polymer is stable under 90.2 ℃ and has three emission peaks at 368, 422 and 484 nm. CCDC: 643626.  相似文献

The hydrogen bonding are observed between 2,2′-bipy and adjacent terminal oxygen atom. It is noteworthy that π-π stacking interaction between adjacent 2,2′-bipy groups plays an significant role in stabilization of the structure of crystal. CCDC: 194327.  相似文献
