polymer [Cu(pyrimidin-2-olate-N1,N3)2]n (1C) of the sodalite zeotype sorbs a variety of metal nitrates [M(NO3)m, M = Na+, K+, Rb+, Tl+, Ca2+, Sr2+, Ba2+, Pb2+, La3+, Nd3+, Gd3+, Er3+] from H2O/MeOH solutions, with a concomitant structural change to a layered [Cu(pyrimidin-2-olate-N1,N3)2]n.[M(NO3)m]n/2 (MNO3@1L) coordination framework. Single-crystal X-ray diffraction analyses revealed that the layers
钠方晶沸石型纳米多孔配位聚合物[Cu(嘧啶-2-油酸酯-N1,N3)2] n(1C)吸收各种金属硝酸盐[M(NO3)m,M = Na +,K +,Rb +,Tl +,由H2O / MeOH溶液制备的Ca2 +,Sr2 +,Ba2 +,Pb2 +,La3 +,Nd3 +,Gd3 +,Er3 +],伴随的结构变化为分层的[Cu(嘧啶-2-油酸酯-N1,N3)2] n] [M( NO3)m] n / 2(MNO3 @ 1L)协调框架。单晶X射线衍射分析表明,这些层基于由N1,N3明显配体桥接的铜(II)离子的Cu4(嘧啶-2-油酸酯-N1,N3)4方形网格,显示出缩锥构型的metallacalix [4]芳烃类型。层间空间被客体金属硝酸盐占据,每种金属都(至少)由金属lacalix [4]芳烃的四个氧原子配位。MNO3 @ 1L系列的磁测量表明,在Neel温度(通常接近35 K)以下发生了弱的铁
