Three alkaline earth metal ions doped Co II heterometallic cluster complexes and one monometallic magnesium cluster complex based on N‐(phosphonomethyl)imino‐diacetic acid (H 4 PMIDA) and 1,3,5‐benzenetricarboxylate acid (H 3 BTC) multifunctional ligands, [Co 13 Mg 2 (PMIDA) 6 (BTC) 2 (H 2 O) 12 ] · 6H 2 O ( 1 ), [Co 13 Ca 2 (PMIDA) 6 (BTC) 2 (H 2 O) 12 ] · 6H 2 O ( 2 ), [CoBa(PMIDA)(H 2 O) 2 ] · H 2 O ( 3 ), and [Mg 15 (PMIDA) 6 (BTC) 2 (H 2 O) 12 ] · 6H 2 O ( 4 ) were synthesized under hydrothermal conditions and characterized by elemental analyses, IR spectroscopy, thermal analyses, and single‐crystal X‐ray diffraction. Compounds 1 , 2 , and 4 are basically isostructural and feature a cubic 3D open framework constructed by [ M 15 (PMIDA) 6 (H 2 O) 12 ] ( M = Co 13 Mg 2 for 1 , Co 13 Ca 2 for 2 , and Mg 15 for 4 ) clusters and BTC 3– ligands. Compound 3 is characterized as a 3D framework containing rings with two tropisms along [010] and [101] directions, which are constructed by BaO 6 chains and CoNO 4 chains. Moreover, solid‐state fluorescent properties of these complexes were also investigated at room temperature, in which compound 4 exhibits the very strong emission band at 411 nm, and might serve as a candidate for hybrid inorganic‐organic fluorescent material.
