In the crystals of trans-diaquobis(my-3-aminopyrazine-2-carboxylato-N,O,O,O)strontium(II) the Sr ion is eightfold coordinated: by two aminopyrazine (APZA) ligands via their (N,O) bonding moieties [Sr-O 2.5189(15) A, Sr-N 2.7280(18) A], two other carboxylate oxygen atoms donated by the adjacent APZA molecules [Sr-O 2.5989(16) A] bridging the Sr(APZA)2 units into molecular ribbons and two water molecules [Sr-O 2.5556(18) A]. The ribbons are interconnected by hydrogen bonds involving the water molecules and the carboxylate oxygens [O-H...O 2.71(1) A], as well as the amino group nitrogen atoms and the heteroring nitrogen atoms [N-H...N 3.08(1) A].
