Syntheses, structures, fluorescence and thermal properties of three lanthanide coordination polymers built by N-benzoyl-N′-(4-benzoxy)thiourea

“…The strong absorption bands at 1660 and 1400 cm À 1 are assigned to n as (COO À ) and n s (COO À ) vibrations, respectively (1: 1678 and 1423 cm À 1 , 2: 1678 and 1378 cm À 1 , 3: 1673and 1412 cm À 1 ), which is close to the reported in the literatures [19][20][21]. The difference between n as (COO À ) and n s (COO À ) is lower than 200 cm -1 , which indicates the m 2 -bridging mode of the carboxylate group to the metal ion.…”
