characterized along with a novel two-dimensional lead nitrate-oxalate of the composition, (OPb2)2(C2O4)(NO3)2, VI. In all these dicarboxylates, there is two-dimensional inorganic connectivity and the lead (II) cation has hemi- or holo-directed coordination geometry. Depending upon the torsional angle and the coordination mode of the dicarboxylate anions as well as the geometry of the lead (II) cations, these
具有混合结构的三维均质剂(单一类型的配体)二羧酸铅,涉及组合物的Pb–O–Pb键,Pb(C 5 H 6 O 4),I和Pb(C 6 H 8 O 4),II和III,已经合成和表征。式为Pb 2(C 2 O 4)(C 4 H 4 O 4),IV和Pb 2(C 2 O 4)(C还制备了6 H 8 O 4),V以及具有涉及Pb–O–Pb键的杂化结构,并对其成分为新型的二维硝酸草酸铅(OPb 2)2(C 2 O 4)进行了表征。)(NO 3)2,VI。在所有这些二羧酸盐中,都有二维无机连接性,并且铅(II)阳离子具有半定向或全定向的配位几何形状。根据二羧酸根阴离子的扭转角和配位方式以及铅(II)阳离子的几何形状,这些杂化化合物表现出两种类型的二维无机连接性。
