Abstract

The adduct of lead(II) bis(di-iso-butyldithiophosphate) and 1,10-phenantroline is a centrosymmetric dimeric supermolecule formed through Pb center dot center dot center dot S secondary interactions. In the monomeric building unit the metal center is six-coordinate (with two nitrogen atoms from 1,10-phenantroline and four sulphur atoms from two different dithiophosphato ligands). In the dimer two additional secondary bonds from lead(II) to sulphur atoms of a second lead(II) dithiophosphate unit raises the coordination number of lead which becomes eight-coordinated. The ligand displays a dimetallic tetraconnective coordination mode. In the crystal the dimers are further interconnected into a bidimensional supramolecular structure through weak S center dot center dot center dot H-C and O center dot center dot center dot H-C bonds between the sulphur and oxygen atoms of a dithiophosphato ligand and 1,10-phenantroline hydrogen atoms from different units.
