Non-covalent tetrel bonding interactions in hemidirectional lead(ii) complexes with nickel(ii)-salen type metalloligands†
Four hetero-dinuclear nickel(II)/lead(II) complexes have been synthesized and characterized. Their structures have been confirmed by single crystal X-ray diffraction studies. In each complex, nickel(II) is placed in the inner N2O2 compartment and lead(II) in the outer O2O2′ compartment of the respective Schiff base. In complexes 1, 3 and 4, lead(II) centres are hemidirectionally coordinated, and thus are well suited for establishing tetrel bonding interactions which have been investigated thoroughly by means of DFT calculations.
