摘要：

A 1D heterometallic Cr-2/Ag-2 polymer formulated as {[Ag(mu-H2O)Ag(nta)Cr(mu-OH)(mu-AcO,O')Cr(nta)]center dot H2O}(n) (1) (H(3)nta = nitrilotriacetic acid) has been prepared and structurally characterized. {Cr(mu-OH)(mu-OAc)Cr} dimeric units containing two different bridging ligands, hydroxo and acetate groups are coordinated to six Ag atoms forming the 10 network. The temperature dependence of magnetic susceptibility for 1 which was fitted with an isotropic Hamiltonian including biquadratic exchange parameters, yielded antiferromagnetic interaction parameters (J = 8.5(1), j = -0.50(7)cm(-1) g = 2.0).
