| Compound 1 was obtained by reaction of salicylidene with 2-amino-2-methyl-1-propanol(salicylidene-amino-2-methyl-1-propanol, H2sal amp),which is a tridentate Schiff base ligand.Compound 2,3 were obtained by reactions of H2salamp with Mn(OAc)2 and CuCl2 respectively. The compound 4,5 were obtained by reactions of the single molecule magnet[Ni4(MeOH)4(sae)4]with p-Phthalic acid under different pH respectively.Compound 6 was obtained by reaction of potassium octa cyanomolybate[K4Mo(CN)8],nickel nitrate and hydet-en[hydet-en is N-(2-hydroxyethyl)ethylenediamine].The formula of 1-6 are as follows:(?) 1Mn(salamp)2 2[Cu(salamp)]4·(CH3)2CO 3{Ni2(Hsae)2[p-C6H4(COOH)2](H2O)2}n 4Ni(C7H5O2)2 5[Ni(C4H12N20)2Ni(CN)4]n 6Compounds 1,2,3,4,5 and 6 were characterized by IR,and the structures of 2,3,4,5 and 6 were determined by X-ray single crystal diffraction.Compounds 3 and 4 have been characterized by temperature dependence of magnetic susceptibilities.Compound 1 is a new tridentate Schiff base ligand,each salamp2- incorporating an(O,N,O) donor. Compouds 2 and 5 are mononuclear complexes.Compound 3 consists of an open cubane-like Cu4O4 core structure units formed by four copper(Ⅱ) ions and four bridging oxygen atoms from H2salamp.Compound 4, which consists of binuclear nickel units bridging by oxygen atoms from p-Phthalic acid,exhibits one-dimensional chain structure and extends to two-dimensional networks through hydrogen bonds.Compound 6 is a linear cyano-bridged homonuclear chain,the chains are linked by hydrogen bonds,generating undulating sheets.The magnetic property of compounds 3,4 indicate that there exist anti-ferromagnetic interaction between metal ions.
