A bis(tridentate) compartmental pyrazolate‐based ligand forms the discrete dizinc(II) complex[LZn 2 (NO 3 ) 3 ] ( 1 ) with a singly O‐atom bridging nitrate and two terminal chelating nitrates. In the absence of coordinating counteranions, the dizinc(II) scaffold takes up atmospheric carbon dioxide to give a tetranuclear species 3 assembled from two dinuclear components. Its X‐ray crystal structure reveals a μ 4 ‐bridging carbonate cap, which is a rare structural motif in zinc(II) coordination chemistry.
