Abstract

A series of new crystal structures of salts containing [PtCl4]2- or [PdCl4]2- with organic cations containing pyridinium and piperidinium groups have been prepared: [4,4'-H2bpe][PtCl4] (2), [4,4'-H2bpethane][PtCl4] (3), [HNC5H4CO2H-4]2[PtCl4] (6a), [HNC5H4CONH2-3]2[PtCl4] (8), [H2NC5H9CO2H-4]2[PtCl4] (9), [H2NC5H9CO2H-3]2[PtCl4] (10), [H2NC5H9CO2H-4]Cl (11), [HNC5H4CO2H-4]Cl (12), [4,4'-H2bpe][PdCl4] (13), [4,4'-H2bipip][PdCl4] (14a, 14b, 14c), [piperazinium][PdCl4]·2H2O (15), and [HNC5H4CO2H-4]2[PdCl4]·2H2O (16). The molecular recognition motifs formed in these and related structures are identified and discussed. The robustness of these supramolecular synthons and their applicability in synthetic crystallography are analyzed. Cases of structural mimicry of a molecule by a supramolecular dication (1 and 6a), isomorphism (2 and 3; 4 and 14a; 6 and 16), polymorphism (14a-c), and "latent" polymorphism (2 and 13) are identified.
