Catena-Poly[(diaqua-strontium)-bis-{?-5-[4-(1H-imidazol-1-yl)phen-yl]tetra-zolido}].

ABSTRACT: In the title complex polymer, [Sr(C(10)H(7)N(6))(2)(H(2)O)(2)](n), the Sr(II) atom lies on an inversion centre and is coordinated by four N atoms from two bidentate bridging trans-related 5-[4-(1H-imidazol-1-yl)phen-yl]tetra-zolide ligands [Sr-N = 2.387?(4)?Å for the tetrazolide moiety and Sr-N = 2.273?(5)?Å for the imidazole moiety], and by two O atoms from water mol-ecules [Sr-O = 2.464?(4)?Å], giving a distorted octa-hedral coordination. Pairs of ligand bridges link the complex units, forming chains which extend along [111] and are inter-associated through O(water)-H?N hydrogen bonds, giving a two-dimensional network structure parallel to (001). Weak ?-? stacking inter-actions between the benzene and imidazole rings are also present [minimum ring centroid separation = 3.691?(4)?Å].
