Catena-Poly[[diaquabis(isoquinoline-κN)cobalt(II)]-μ-succinato-κ2O1:O4

Abstract

In the title compound, [Co(C4H4O4)(C9H7N)2(H2O)2]n, the CoII cation, located on an inversion center, is coordinated by two succinate anions, two isoquinoline ligands and two water mol­ecules in a distorted octa­hedral geometry. The succinate anion, located across another inversion center, bridges the Co cations, forming polymeric chains running along the b axis. The partially overlapped arrangement of parallel isoquinoline ring systems of adjacent polymeric chains and the shorter face-to-face distance of 3.402 (6) Å indicates the existence of weak π–π stacking in the crystal structure. Classical intra- and inter­molecular O—H⋯O hydrogen bonding and weak non-classical inter­molecular C—H⋯O hydrogen bonding help to stabilize the crystal structure.
