Syntheses, Structures, Luminescence, and Gas Adsorption Properties of Two New Heterometallic Complexes Involving Alkaline Earth Metals (Ca, Ba)

Two new 3D heterometallic frameworks, [Me 2 NH 2 ][CaCd 2 (BTC)(HBTC) 2 ] · 4H 2 O ( 1 ) and [Ba 11 Co 2 (BTC) 8 (μ 3 ‐OH) 2 (μ 2 ‐H 2 O) 6 (H 2 O) 16 ] ( 2 ) (H 3 BTC = 1,3,5‐benzenetricarboxylic acid, Me 2 NH 2 = protonated dimethylamine), were synthesized using solvothermal and hydrothermal techniques, respectively. Complex 1 features a 3D microporous framework; it contains hourglass‐like trinuclear [CaCd 2 (COO) 6 ] clusters that are bridged...
