A COMPLEX OF Zn(II) WITH CHIRAL NOPINANE-ANNELATED 9,9′-bi-4,5-DIAZAFLUORENYLIDENE: SYNTHESIS, STRUCTURE, AND PROPERTIES

Complex ZnLCl 2· EtOH·H 2 O ( I ) where L is chiral 9,9′-bi-4,5-diazafluorenylidene containing fragments of natural monoterpenoide (–)-α-pinene is synthesized. The crystal structure of I is composed of ZnLCl 2 mononuclear complex, solvate EtOH, and H 2 O molecules. The coordination polyhedron Cl 2 N 2 of the Zn atom is a distorted tetrahedron. L is a bidentate cyclic ligand, involving only two N atoms in the coordination. Complex I is characterized by IR and NMR spectroscopy and its thermal properties are analyzed. In the solid phase, L exhibits photoluminescence is the visible range (λ max = 610 nm).
