摘要:
A mononuclear manganese complex [Mn(2,2′-bipy)(H20) 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, D c=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.

The title complex [^n BuSn(O)O2C(OH)CPh2]6.2H2O has been synthesized by the reaction of n-BuSn(O)OH with benzilic acid in 1:1 molar radio and characterized by IR, ^1H NMR spectra and elemental analysis. The crystal structure was determined by X-ray diffraction. It crystallizes in triclinic, space group PI with a = 1.3543(2), b = 1.4593(2), c = 1.5293(2) nm, α = 102.075 (2),β = 115.571 (2), γ = 93.308(3)°, Z = 1, V = 2.6282(7) nm^3, Mr = 2550.21, Dc = 1.611 g/cm^3,μ = 1.477 mm^-1, F(000) = 1280, R = 0.0309 and wR = 0.0729. The structure shows a distorted octahedral configuration with six-coordination for the central tin atom.
