| Abstract: | Homobinuclear complex (HCuL)2 ( 1 ) (H3L: N‐3‐carboxylsalicylidene‐N′‐salicylaldehyde‐1,2‐diaminoethane) was obtained from self‐organization of the reported complex HCuL, and its crystal structure was determined through X‐ray diffraction at room temperature. The crystal of complex 1 belongs to monolinic system, the space group Cc, a=2.5326(5) nm, b=0.88861(18) nm, c=1.3738(3) nm, β=96.95(3)°, Z=4, R1=0.0520, wR2=0.1185. (HCuL)2 is a dimeric molecule and has extended phenolic oxygen‐bridged structure. In addition, using mononuclear complex HCuL as building blocks, Cu(II)‐Mg(II)‐Cu(II) heterotrinuclear complex 2 was synthesized, and its crystal structure also has been determined by X‐ray analysis. The crystal of complex 2 is of monoclinic system, space group Pc, a=1.1816(2) nm, b=1.5599(3) nm, c=1.9642 (4) nm, β=98.22°, Z=2, R1=0.0701, wR2=0.1498. Each dissymmetrical cell unit of complex 2 contains two heterotrinucler neutral molecules: {CuL(H2O)]MgCuL(CH3OH)]} and {CuL]MgCuL(H2O)]}. |
