Summary, etc. <p>Organic-inorganic hybrid of 3<em>d</em>-4<em>f</em> heterometallic derivatives of lacunary Keggin type silico- and germano-tungstates: [{Cu<sub>2</sub>(1,10-phen)<sub>2</sub>(<em>µ</em>-CH<sub>3</sub>COO)<sub>2</sub>}Ln(α-XW<sub>11</sub>O<sub>39</sub>)<sub>2</sub>]<sup>11‒/10‒</sup> {Ln = La<sup>III</sup>, Ce<sup>III</sup> and Ce<sup>IV</sup>, X = Si<sup>IV</sup>; La<sup>III</sup>, Ce<sup>III</sup>, Ce<sup>IV</sup>, X = Ge<sup>IV</sup>; 1,10-phen = 1,10-Phenanthroline} have been synthesized by conventional aqueous solution method under mild reaction conditions. Solid crystalline materials isolated from the solution as an alkali salts (Na<sup>+</sup>/K<sup>+</sup>) are characterized by single crystal X-ray diffraction, FT-IR spectroscopy, powder-XRD, ICP-AES, liquid UV/vis and thermogravimetric analysis. FT-IR spectra and PXRD suggest that these compounds are isomorphous. Further, single crystal XRD analyses show that all are organic-inorganic hybrids comprising Peacock and Weakley type sandwich-type [Ln(α-XW<sub>11</sub>O<sub>39</sub>)<sub>2</sub>]<sup>13−/12‒</sup> (X = Si<sup>IV</sup> and Ge<sup>IV</sup>) polyanion as the fundamental building block unit. These sandwich type species form polymeric chain assistance with copper organic complexes. These polymeric chains further assemble into 2-D structures by π-π stacking.</p>
