Abstract Reactions of 2,6-diisopropylphenyl phosphate (dippH2) with group 12 metal acetates [M(OAc)2•2H2O (M= Zn, Cd, Hg)] in the presence of hexadentate auxiliary N-donor ligand, 2,3,5,6-tetra-(2-pyridyl)pyrazine (tppz), produce binuclear tppz bridged complexes [M(tppz)(dippH)2]2.H2O (M= Zn (1), Hg (2)) and [Cd(tppz)(dippH)2.H2O]2.MeOH (3), as single crystals. Compounds 1–3 have been characterized by microanalysis and FT-IR, ESI-MS, and CP- MAS 31P NMR spectroscopy and thermal decomposition studies. The molecular structures of 1–3 have further been established by single crystal X-ray diffraction studies which reveal that all the three binuclear complexes exhibit extensive hydrogen bonding interactions due to the presence of uncoordinated P OH groups and lattice water molecules, leading to the formation of 1D and 2D polymeric architectures.
