| 中文摘要 | four new polymeric lanthanide(iii) complexes of nicotinic acid n-oxide and isonicotinic acid n-oxide have been synthesized and structurally determined. in the isomorphous compounds [(ln(l-1)(3) (h2o)(2))(n)]. 4nh(2)o(hl1 = nicotinic acid n-oxide; ln = eu, 1; ln = er, 2) the lanthanide(iii) ions form infinite double chains along the b direction through the coordination of bridging carboxylate and n-oxide groups. the chains are cross-linked through hydrogen bonds between aqua ligands and uncoordinated n-oxide groups and between aqua ligands and lattice water molecules, to form a three-dimensional network. [(eu(l-2)(2)-(h2o)(4))(n)](no3)(n). nh(2)o (hl2 = isonicotinic acid n-oxide, 3) has a polymeric structure in which the europium (iii) ions are connected into infinite chains by pairs of syn-syn carboxylate groups. adjacent chains are interlinked by hydrogen bonds between aqua ligands and n-oxide groups to form a layer parallel to the (100) plane, and such layers are connected by hydrogen bonds between nitrate anions and aqua ligands, and between oxide groups and lattice water molecules, into a three-dimensional network. in [(er-2(l-2)(4)(h2o)(10))](no3)(2). h2o, 4, dinuclear units are inter-linked into a three-dimensional network through hydrogen bonding between aqua ligands and n-oxide groups of both bidentate bridging and unidentate l-2 ligands. factors affecting the formation of coordination chains and dinuclear units are discussed. luminescence properties of 1 and 3 have also been studied.
