| 摘 要： | Reactions of lead（Ⅱ） nitrate or perchlorate with bis（3,5-dimethylpyrazolyl）methane （dmpzm）, produced two new Pb（Ⅱ） chelated complexes Pb（dmpzm）2X2] （X=NO3^- 1, ClO4^- 2）. Both compounds were structurally characterized by elemental analysis, IR spectroscopy, thermal analysis, and single crystal X-ray diffraction. Both compounds are mononuclear with a distorted square antiprismatic PbN4O4 coordination geometry incorporating a pair of O,O＇-bidentate anions and N,N＇-bidentate dmpzm ligands. In the crystals of 1 or 2, the methyl or methylene groups of dmpzm ligand interact with the oxygen atoms of nitrates or perchlorates to afford intra- and intermolecular hydrogen bonding, thereby forming a two-dimensional network 1 or a three-dimensional structure 2.

| Abstract: | Reactions of lead(II) nitrate or perchlorate with bis(3,5‐dimethylpyrazolyl)methane (dmpzm), produced two new Pb(II) chelated complexes Pb(dmpzm)2X2] (X=NO?3 1 , ClO?4 2 ). Both compounds were structurally characterized by elemental analysis, IR spectroscopy, thermal analysis, and single crystal X‐ray diffraction. Both compounds are mononuclear with a distorted square antiprismatic PbN4O4 coordination geometry incorporating a pair of O,O′‐bidentate anions and N,N′‐bidentate dmpzm ligands. In the crystals of 1 or 2 , the methyl or methylene groups of dmpzm ligand interact with the oxygen atoms of nitrates or perchlorates to afford intra‐ and intermolecular hydrogen bonding, thereby forming a two‐dimensional network 1 or a three‐dimensional structure 2 . |
