Syntheses, crystal structures of five supramolecular halides/pseudohalides: (BPP)[CdI_4], (BPP)[HgBr_4], (BPP)[Hg(SCN)Br_3], (BPP)[ZnBr_(0.32)Cl_(0.68)(NCS)_3], and (BPP)[Fe(CN)_6]·2.5H_2O directed by 1,3-bis(pyridinium) propane cation

摘要

Five supramolecular compounds (BPP)[CdI_4] 1, (BPP)[HgBr _4] 2, (BPP)[Hg(SCN)Br_3] 3, (BPP)[ZnBr _(0.32)Cl_(0.68)(NCS)_3] 4, and (BPP)[Fe(CN) _6]·2.5H_2O 5 (BPP = 1,3-bis(pyridinium) propane) were synthesized and characterized by IR spectrum and X-ray crystallography. The crystal structures of 1-3 show that they all crystallize in monoclinic systems with mononuclear tetrahalidometallate structure. Compound 4 crystallizes in triclinic system, space group P-1 in which three SCN- ions serve as bridging ligands to link one Zn(II) ions, giving rise to a approximate tetrahedron. Compound 5 crystallized in a monoclinic system and the Fe ~(2+) center resided in a slightly distorted octahedral environment and was six-coordinated by six SCN~- ions.
