资源简介：
A series of homochiral lanthanide nicotinate helical coordination polymers [LnIII(nic)2(Hnic)(NO3)] (Ln = Eu (1), Gd (2), Tb (3); Hnic = nicotinic acid) has been solvothermally synthesized using nicotinic acid. In the resulting chains, chirality is not induced by a chiral agent but appears spontaneously via intrachain hydrogen bondings. Compounds 2 and 3 were magnetically characterized, and luminescent properties were observed for compounds 1 and 3.
