Abstract
In the title complex, [SmZn(C19H20N2O4)(NO3)3(CH3OH)2]·2CH3OH, the ZnII ion is six-coordinated by two O atoms and two N atoms of the deprotonated Schiff base ligand and by two O atoms from methanol molecules, forming a slightly distorted octahedral geometry. The SmIII ion is coordinated by six O atoms from three chelating nitrate ligands and four O atoms from the Schiff base ligand, forming a distorted bicapped square-antiprismatic environment. In the crystal, intermolecular O—H⋯O hydrogen bonds connect the complex molecules and the two methanol solvent molecules, forming (10) sheets.

The title complex, (I), formed with the Schiff base N,N′-bis(2-hydroxy-3-methoxybenzylidene)-1,3-diaminopropane is dinuclear with the SmIII and ZnII atoms linked through two phenolate O atoms from the ligand, and is the same as the bonding in the isostructural PrIII/NiII complex (Liu & Zhang, 2008) and the SmIII/NiII complex (Liu, 2009) with the same ligand as well as a related SmIII/CuII complex (Wang et al, 2008)
