| Abstract: | Ten new complexes, Cu2(L1)(NO3)2]·2H2O (1), Cu4(L1)2]·4ClO4·H2O (2), Cu2(L1)(H2O)2]·(adipate) (3), Cu6(L1)2(m-bdc)4]·2DMF·5H2O (4), Cu2(L1)(Hbtc)]·5H2O (5), Cu2(L1)(H2O)2]·(ntc)·3H2O (6), Co2(L2)]·Co(MeOH)4(H2O)2] (7), Co3(L2)(EtOH)(H2O)] (8), Ni6(L2)2(H2O)4]·H2O (9) and Zn4(L2)(OAc)2]·0.5H2O (10), have been synthesized. 1 displays a Cu2(L1)(NO3)2] monomolecular structure. 2 shows a supramolecular chain including Cu2L1]2+. In 3, two Cu(II) ions are connected by L1 to form a Cu2(L1)(H2O)2]2+ cation. In 4, the m-bdc anions bridge Cu(II) ions and L1 anions to form a layer. Both 5 and 6 display 3-D supramolecular structures. 7 consists of both Co2L2]2? and Co(MeOH)4(H2O)2]2+ units. 8 and 9 show infinite chain structures. In 10, Zn(II) dimers are linked by L2 to generate a 3-D framework. The magnetic properties for 4 and 8 and the luminescent property for 10 have been studied. |
