Two　types　of　palladium(Ⅱ)-based　metallacalixarenes　[ML]2+and　[ML2]2+have　been　synthesized　through　coordination-driven　self-assembly　from　a　series　of　flexible　pyridine-bridged　diimidazole　ligands　[2,6-bis　((1H-imidazol-1-yl)methyl)　pyridine　(L1),　2,6-bis((1H-benzo[d]imidazol-1-yl)methyl)pyridine　(L2),　2,6-bis((1H-naphtho[2,　3-d]imidazol-1-yl)methyl)pyridine　(L3)],　with　palladium(Ⅱ)-based　building　blocks　[Pd(BF4)2(M1-BF4)　and　(tmeda)Pd(NO3)2　(M2-NO3)　(tmeda　=　N,N,N　,N-tetramethyl-ethylenediamine)].　All　complexes　were　characterized　by　NMR　spectroscopy　(1H　NMR　and　13C　NMR),　mass　spectrometry　(CSI-MS,　ESI-HRMS)　and　elemental　analysis.　The　single　crystal　X-ray　diffraction　analysis　of　[M1L22](NO3)2,　[M1L32](NO3)2,　[M1L32](PF6)2　and　[M2L3](NO3)2　further　confirmed　the　uniquely　single　bowl-shape　and　double　bowl-shape　structures.　The　anion　binding　properties　within　the　metallacalixarenes　as　receptors　were　also　investigated　by　NMR　titration　experiments　in　DMSO.
