Abstract: By the employment of hydrothermal methods, four lead 1,3-cyclohexanedicarboxylates with the compositions Pb(1,3-CHDC)(H2O), I, [(OPb4)2(OH)2(C2O4)(1,3-CHDC)4]‚H2O, II, Pb2(1,3-CHDC)2(H2O), III, and (OPb3)(1,3-CHDC)2, IV, have been prepared and characterized. Of these, I and II have layered structures while III and IV have three- dimensional structures. I−III are hybrid structures possessing extended inorganic connectivity in one or two-dimensions (In, n ) 1 or 2) involving infinite Pb−O−Pb linkages along with zero or one-dimensional organic connectivity (Om, m ) 0 or 1). I contains two types of layers with different connectivities (I1O1 and I2O0). III is a truly 3-D hybrid compound with I2O1 type connectivity. IV has three-dimensional organic connectivity (O3) but no inorganic connectivity (I0). The conformation of the CHDC anion is e,e in I−III and a,e in IV. In all these compounds, the lead atom has hemi- or holodirected coordination geometry.
