Abstract:
The reactions of the new nitrilotriacetic acid N ′, N ′, N ′‐tri(salicyloyl)trihydrazide (Ntash) with the corresponding metal salts gave four new complexes [Pb 4 (bshz) 2 ] · 2DMF ( 1 ), [Co 2 (bshz)(C 5 H 5 N) 6 ] · 2ClO 4 · (C 5 H 5 N) · 2H 2 O ( 2 ), [Cu 3 (fshz) 2 (C 5 H 5 N) 2 ] ( 3 ), and [Zn 3 (fshz) 2 (C 5 H 5 N) 3 ] n · 2DMF ( 4 ), in which two multidentate ligands, namely N , N ′‐disalicyloylhydrazine (H 4 bshz) and N ‐formylsalicylhydrazide (H 3 fshz) were generated in situ from Ntash. The structures of these complexes were determined by single‐crystal X‐ray diffraction analysis. Complex 1 presents a novel tetranuclear lead(II) cluster structure with the four lead(II) cations in “hemidirected” coordination spheres. The neighboring tetranuclear clusters of 1 are connected by DMF molecules through weak Pb–O bonds, forming one‐dimensional ribbons. Complexes 2 and 3 show dinuclear and linear trinuclear structures with the corresponding Co III and Cu II ions in distorted octahedral and square‐planar coordination environments, respectively. Complex 4 exhibits a one‐dimensional zigzag chain structure. The magnetic properties of 3 and the photoluminescent properties of 4 were also investigated.
