| All fields of molecular material, the carboxylic acid coordination polymer was promised with a good future, for it has been widely used in non-line optical, magnetic and coating material. While Schiff base complex has been always interested people because it can be used as anticancer, antibacterial and catalytic activity agent. Furthermore, Studying on carboxylic acid coordination polymer and Schifbase complex can abundant and develop coordination chemistry, afford reference and supervise on the exploit of molecular material and new drug. It's reported that carboxylic acid may adopt six coordinating modes when they coordinate the metal ions, Not only can they be coordinated with one O atom or two O atoms, but also they can coordinate one or two metal ions respectively. With comparable ligand in the corresponding condition, we synthesis the complexes that includs three coordinating modes of them. It's very significant for us to explore the coordinating mode under different condition. Besides, the research on the crystal structure of Schiff base complex can help us discover the antibacterial mechanism of Schiff base drug.By using the solvent-thermal synthetic technology in domestic and combinating solution culturing method, we prepared twelve complexes of crystal, which have not been reported. Chapter one: Compound (1)[Cu2(3,3'-ADB)(PPH3)] belongs to crystal system monoclinic, spare group P21 /c,with cell parameters: a=14.511(2)?, b=13.737(3)?, c=18.305(3)?, V=3601.4(10) ?3, Z=4 , Dc=1.332 mg/cm3. The crystal structure adopts distorted tetrahedron geometry. The copper (I) center is four-coordinated and surround by two oxygen from carboxylic acid and two phosphine atoms from triphenyl phosphine. The compound is a three-dimension layer complex of infinite length connecting with π-π packing layer.Compound (2)[Cu2 (3,3'-AXDB)(PPH3)2]n belong to crystal system monoclinic, space group P21 /c, with cell parameters: a=15.152(3)?, b=12.764(2) ?, c=22.213(4) ?, Z=4, Dc=1.478g/cm3. The coordination geometry around Cu (I) is a distorted tetrahedron, with coordination number three. Different from compound 1, the two oxygen atoms from carboxylic acid coordinate two Cu (I) ions respectively, thus a eight-member-ring formed with two Cu (I) ions, four oxygen atoms and two carbon atoms from two carboxylic acid. The compound is a one dimensional chain complex of infinite length connecting with bridging oxygen atoms from carboxylic acid.Chapter two: Compound (3)[Cd (4,4'-ADB)(H2O)2]n belongs to crystal system monoclinic, space group P21 /m with cell parameters: a=5.5357(8)?, b=24.334(3)?, c=6.0750(8) ?,β=116.127o, , Z=2, Dc=1.883g/cm3. The crystal structure adopts distorted octahedron geometry with six coordination number, the Cd (II) center surrounded by three oxygen atoms from three different carboxylic acid group; The complex is a two dimensional polymer of infinite length connecting with bridging oxygen from carboxylic acid.In the same reaction condition, adding up phen to the substrate, we synthesis a novel coordination polymer [Cd(4,4'-ADB)3(phen)(H2O)] (4), which was completely different from compound (3). The crystal belongs to crystal system, monoclinic, space group P21 /c, with cell parameters: a=16.6386(7)?, b=6.3953(3) ?, c=27.2889(10) ?,β=112.700(2) o,Z=4, Dc=1.430g/cm3. In the polymer, the Cd (Ⅲ) ion adopts octahedron geometry with coordination number six. In the unit cell, the Cd (Ⅲ) bridglinkages three carbopxylic acid through monodentating mode, simutaniously chelates two N atoms of the phen to form a stable five-member ring. These configurational base units make up of a two dimensional coordination polymer.Chapter three: Compound [Ag (C18H14N4)(NO3)](5) belong to crystal system triclinic, spare group P, the crystal structure adopts triangle planar geometry. The Ag (I) center chelates two nitrogen atoms from the Schiff base and pyridine to form a stable five-member ring .The compound is a three dimensional net complex of infinite length connecting with hydrogen...
