Carbon monoxide reacts at atmospheric pressure and temperature with trans-Pt(OH)(C6H5)(PEt3)2 (1) to give a metallacarboxylic acid, trans-Pt(CO2H)(C6H5)(PEt3)2 (2).Crystals of 2 are monoclinic, space group C2/c, a = 15.006(2) Angstroem, b = 11.520(2) Angstroem, c = 27.135(6) Angstroem, β = 89.90(1) degree, Z =8, at 175 K.The structure was solved by heavy atom methods and refined by least-squares techniques to R = 0.033 (Rw = 0.038) for 3070 unique data (I > 3?(I)).It consists of a dimer in which two planar trans-Pt(CO2H)(C6H5)(PEt3)2 units are joined by hydrogen bonding between the carboxylate groups.This structure, the O-H...O distance of 2.695 Angstroem, and the metrical data for the carboxylate group
