Crystal Synthesis of Organic-Inorganic Hybrid Salts Based on Tetrachloroplatinate and -palladate Salts of Organic Cations: Formation of Linear, Two-, and Three-Dimensional NH···Cl Hydrogen Bond Networks

摘要: A series of new crystal structures salts containing [PtCl4]2- or [PdCl4]2- with organic cations 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), [HNC5H4CO2H-4]2[PdCl4]·2H2O (16). The molecular recognition motifs formed in these related are identified discussed. robustness supramolecular synthons their applicability synthetic crystallography analyzed. Cases structural mimicry a molecule by dication (1 6a), isomorphism (2 3; 4 14a; 6 16), polymorphism (14a−c), “latent” 13) identified.
