| Abstract: Two novel mononuclear complexes [Cu(phen)(Ts-α-ala)2(H2O)] (1) and [Mn(phen)(Ts-α-ala)(HCOO)(H2O)2] (2) were isolated from the mixed solvent reaction of N-p-Tolylsulfonyl-α-Alanine(Ts-α-Hala), 1,10-phenanthroline (phen) and CuCl2·2H2O (or MnCl2·4H2O), and characterized by elemental analysis, IR, TG and single-crystal X-ray diffraction analysis. Complex 1 is triclinic system, space group P1 with the cell parameters: a=1.174 6(2) nm, b=1.182 8(2) nm, c=1.493 6(3) nm, α=70.22(3)°, β=88.26(2)°, γ=62.14(3)°, V=1.706 0(8) nm3, Z=2, F(000)=774, R1=0.055 3, wR2=0.118 9; The coordination polyhedron of copper ion is distorted square pyramidal. The intermolecular hydrogen bonds results in the structure of one-dimensional supramolecular chain of the complex. The complex 2 is monoclinic system, space group P21/c with the cell parameters: a=2.394 4(2) nm, b=0.992 92(11) nm, c=1.080 29(11) nm, β=92.750(2)°, V=2.565 4(4) nm3, Z=4, F(000)=1 152, R1=0.056 9, wR2=0.110 5. The manganese ion is in a geometry of distorted octahedral built by six coordination atoms. There are a lot of hydrogen bonds in the complexe, forming a two-dimensional layered supramolecular structure. CCDC: 754579, 1; 754578, 2. |
