A manganese coordination polymer Mn(3,5-Me2PhCO2)2(phen)n(phen=1,10-phenanthroline) has been synthesized by hydrothermal methods. The crystal structure was determined by single-crystal X-ray diffraction. The crystal is of triclinic, space group P1 with a=0.770 3(4) nm, b=1.145 2(6) nm, c=1.537 0(9) nm, α=78.182(9)°, β=77.170(9)°, γ=89.784(9)°, V=1.292 8(12) nm3, Z=2, Mr=533.47, Dc=1.370 g·cm-3, μ=0.549 mm-1, F(000)=554, Rint=0.043 4, R=0.060 8 ,wR=0.148 4. In the crystal the manganese atom is six-coordinated by two nitrogen atoms from phen and four oxygen atoms from four 3,5-dimethylbenzolate molecules, completing an octahedral geometry. And the title complex forms one-dimensional chain structure through bridging 3,5-dimethylbenzolate molecules. CCDC: 642920.
The title complex {[nBu2Sn(2-OHC6H4CH=NC6H4COO)]2O}2·2H2O was synthesized by the reaction of N-(4-carboxyphenyl)-salicylideneimine with dibutyltin(Ⅳ) oxide in 1∶1 molar ratio. The compound has been characterized by elemental analysis, IR, 1H NMR spectra and X-ray single crystal diffraction. It crystallizes in triclinic system with space group P1. The crystal data are: a=1.242 9(2) nm, b=1.261 3(2) nm, c=1.594 9(3) nm, α=102.06(2)°, β=92.884(3)°, γ=95.939(3)°, Z=2, Dc=1.342 g·cm-3, F(000)=1 000, V=2.425 2(7) nm3, R1=0.041 5, wR2=0.104 4. The compound is in centro-symmetric dimer structure mode with a four-member central endo-cyclic Sn2O2 unit in which the bridging oxygen atoms are tri-coordinated. All the tin atoms are five-coordinated with geometry of distorted trigonal bipyramid. CCDC:286105.
