Using predesigned tetrahedral quadridentate linker tetrakis(4-pyridyloxymethylene) methane (TPOM) as the organic linker, tetrahedral P1 clusters ([Cd8S(SPh)(16)](2-)) and C1 clusters ([Cd17S4(SPh)(28)](2-)) have been assembled into beltlike (MCOF-9) or chainlike (MCOF-10) configurations, as determined by single-crystal X-ray diffraction. The onset of optical absorptions of MCOF-9 and MCOF-10 is around 400 and 420 nm, respectively. The thermal analysis shows that both materials are stable up to 250 degrees C.
