-isobutyrato-bis[cis-diammineplatinum(II)]} tetraperchlorateAbstract: The title compound, [Pt2(-C4H7O2)2(NH3)4]2(ClO4)4, involves two independent diplatinum(II) units. For each unit, a pair of dimeric units located around an inversion center are associated with one another to give a tetranuclear PtII4 cation, in which the interdimer association is stabilized by four hydrogen bonds formed between the ammines and the butyrate O atoms. The intradimer and interdimer Pt-Pt distances within these tetraplatinum(II) chain cations are, respectively, 2.9881 (4) and 3.2619 (6) Å for one set of dimers, and 3.0246 (4) and 3.3049 (6) Å for the other set of dimers.
