Dalton communications. Molecular zinc oxide and sulfide complexes stabilized by pyrazolylborate ligands
Abstract
The highly encapsulating tris (3-p-cumenyl-5-methylpyrazolyl)borate L and its isomer L′ have been found to create sufficient steric hindrance and electronic saturation to stabilize non-oligomeric Zn–O–Zn and Zn–S–Zn units in the neutral dinuclear complexes [(L′Zn)2O] and [(LZn)2S], the crystal structures of which were determined.
