Abstract
Two two-dimensional coordination complexes, {[Cu4(BTM) 6(OPA)4]·4DMF·3H2O} n (1) and {[Cu(BDTM)(OH)](ClO4)·2H2O} n (2) (BTM = bis(1,2,4-triazol-1-yl)methane, BDTM = bis(3,5-dimethyl-1,2,4- triazol-1-yl)methane, OPA2- = ortho-phthalic dianion, DMF = N,N-dimethylformamide), were synthesized and structurally characterized. Each Cu(II) ion locates in a distorted square pyramidal geometry in 1, in which OPA2- ligands bridge Cu2+ ions along a axis to form a magnetic transmission chain and BTM ligands act as flexible spacers to construct the two-dimensional layer structure. In 2, each Cu2+ ion adopts tetra-coordination geometry to two hydroxyl groups and two triazolyl nitrogen atoms from two different BDTM ligands. Two hydroxyl groups bridge two Cu 2+ ions to form a rhombic diamond, and four BDTM ligands connect four diamonds to form a 36-membered macrocyclic structure with large channels along a axis. Magnetic properties revealed that both OPA2- and OH - mediate anti-ferromagnetic interactions between Cu2+ ions with J = - 0.06(3) and -301.9(2) cm-1 for 1 and 2, respectively.
