Intermolecular hydrogen bonding in isostructural pincer complexes [OH-(t-BuPOCOPt-Bu)MCl] (M = Pd and Pt)

In the crystal structure of the isostructural title compounds, namely {2,6-bis[(di- tert -butylphosphanyl)oxy]-4-hydroxyphenyl}chloridopalladium(II), [Pd(C 22 H 39 O 3 P 2 )Cl], 1 , and {2,6-bis[(di- tert -butylphosphanyl)oxy]-4-hydroxyphenyl}chloridoplatinum(II), [Pt(C 22 H 39 O 3 P 2 )Cl], 2 , the metal centres are coordinated in a distorted square-planar fashion by the POCOP pincer fragment and the chloride ligand. Both complexes form strong hydrogen-bonded chain structures through an interaction of the OH group in the 4-position of the aromatic POCOP backbone with the halide ligand.
