The title complex has been synthesized with 2,2'-biphenyl dicarboxylic acid and 1,10-phenanthroline(phen)in the solvent mixture of water and methanol.It crystallizes(C38H28CuN4O6,Mr = 700.1)in triclinic,space group P1 with a = 1.0868(2),b = 1.2175(2),c = 1.6206(3)nm,α = 110.161(2),β = 102.605(3),γ = 93.667(2)o,V = 1941.6(6)nm3,Dc = 1.198 g/cm3,Z = 2,F(000)= 722,R = 0.0558 and wR = 0.1208.The crystal structure shows that the copper atom is coordinated with one oxygen atom from 2,2'-bphenyl dicarboxylic acid molecule and four nitrogen atoms from two 1,10-phenanthroline molecules,forming a distorted square-pyramidal coordination.The TG analysis shows that the title complex is stable under 160.0 ℃. 展开更多

A new manganese(Ⅱ) complex [Mn(C_(14)H_(9)O_(3))_(2)(C_(12)H_(8)N_(2))_(2)]·4H_(2)O(1) was synthesized with o-benzoylbenzoic acid, manganese sulfate and 1,10-phenanthroline(phen) in the mixture of acetonitrile a... A new manganese(Ⅱ) complex [Mn(C_(14)H_(9)O_(3))_(2)(C_(12)H_(8)N_(2))_(2)]·4H_(2)O(1) was synthesized with o-benzoylbenzoic acid, manganese sulfate and 1,10-phenanthroline(phen) in the mixture of acetonitrile and water solvent. It crystallizes(C_(52)H_(42)MnN_(4)O_(10), M_(r) = 937.83) in monoclinic, space group P2_(1/n) with a = 13.3528(5), b = 17.6963(6), c = 19.7889(7) A, β = 109.647(4)o, V = 4403.8(3) A3, D_(c) = 1.415 g/cm^(3), Z = 4, F(000) = 1948, μ(Mo Kα) = 0.368 mm^(-1), R = 0.0404 and w R = 0.0956. The crystal structure shows that the manganese ion is coordinated with two oxygen atoms from two o-benzoylbenzoic acid molecules and four nitrogen atoms from two phen molecules, forming a distorted octahedral coordination geometry. The TG, spectrum analysis and magnetic properties of 1 were studied. 展开更多
