Two new coordination complexes[Mn(L)2(DNSA)](1) and[Co(L)(1,4-bdc)]n (2) have been achieved under hydrothermal conditions (H2DNSA =3,5-dinitro-salicylic acid,1,4-bdc =1,4-benzenedicarboxylic acid and L =2-(2-fluoro-6-fluorophenyl)-1H-irnidazo[4,5-f][1,10]phenanthroline).1 crystallizes in monoclinic,space group P21/c with a =15.871(3),b =17.274(4),c =16.078(3) (A),β =113.03(3)°,V=4056.6(16) (A)3,Z =4,C45H22Cl2F2MnN10O7,Mr =978.57,Dc =1.602 g/cm3,F(000) =1980,μ(MoKa) =0.536 mm-1,R =0.0437 and wR =0.1065.2 belongs to the monoclinic system,space group C2/c with a =14.665(2),b =30.856(4),c =11.237(2) (A),β =111.166(2)°,V =4742.0(12) (A)3,Z =8,C27H14ClCoFN4O4,Mr =517.80,Dc =1.602 g/cm3,F(000) =2312,μ(MoKa) =0.889 mm-1,R =0.0364 and wR =0.0862.The central Mn(Ⅱ) ion in 1 is six-coordinated by four nitrogen atoms from two L ligands and two oxygen atoms from one DNSA anion.In 2,the two kinds of 1,4-bdc ligands link neighboring Co(Ⅱ) atoms to yield a two-dimensional layer structure.The luminescence of 1 has been studied in detail.Moreover,thermal behaviors of 1 and 2 are also investigated.
