The crystal structures of five new transition‐metal complexes synthesized using thiazole‐2‐carboxylic acid (2‐Htza), imidazole‐2‐carboxylic acid (2‐H 2 ima) or 1,3‐oxazole‐4‐carboxylic acid (4‐Hoxa), namely diaquabis(thiazole‐2‐carboxylato‐κ 2 N , O )cobalt(II), [Co(C 4 H 2 NO 2 S) 2 (H 2 O) 2 ], 1 , diaquabis(thiazole‐2‐carboxylato‐κ 2 N , O )nickel(II), [Ni(C 4 H 2 NO 2 S) 2 (H 2 O) 2 ], 2 , diaquabis(thiazole‐2‐carboxylato‐κ 2 N , O )cadmium(II), [Cd(C 4 H 2 NO 2 S) 2 (H 2 O) 2 ], 3 , diaquabis(1 H ‐imidazole‐2‐carboxylato‐κ 2 N 3 , O )cobalt(II), [Co(C 4 H 2 N 2 O 2 ) 2 (H 2 O) 2 ], 4 , and diaquabis(1,3‐oxazole‐4‐carboxylato‐κ 2 N , O 4 )cobalt(II), [Co(C 4 H 2 NO 3 ) 2 (H 2 O) 2 ], 5 , are reported. The influence of the nature of the heteroatom and the position of the carboxyl group in relation to the heteroatom on the self‐assembly process are discussed based upon Hirshfeld surface analysis and used to explain the observed differences in the single‐crystal structures and the supramolecular frameworks and topologies of complexes 1 – 5 .
