Dichlorido{μ-6,6′-dimethoxy-2,2′-[o-phenylenebis(nitrilomethylidyne)]diphenolato}(dimethyl sulfoxide)lead(II)zinc(II)N,N-dimethylformamide solvate

Abstract

In the heterodinuclear complex of the title compound, [PbZn(C22H18N2O4)Cl2(C2H6OS)]·C3H7NO, the ZnII atom is coordinated in a distorted square-pyramidal geometry by two N atoms and two O atoms from the diphenolate ligand, and one Cl atom which occupies the apical position. The PbII atom is coordinated in a distorted octa­hedral geometry by the four O atoms of the diphenolate ligand, one O atom from the dimethyl sulfoxide mol­ecule and one Cl atom. The dimethyl sulfoxide mol­ecule is disordered over two positions, with site occupancies of 0.576 (2) and 0.424 (2).

“…The isolated compounds were formulated as LMM / X [18] or LMLnX [19][20][21][22][23][24][25], where L stands for the ligand, M for the 3d ion (mainly Zn(II) and Cu(II)), M / for alkali metals, Ln for the 4f metals, and X for the anionic species [26,27]. To the best of our knowledge, there are no reports on the preparation of trinuclear cationic M 2 M / compound with a ClO 4 − as the counter ion.…”
