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