title: Poly[[μ-aqua-bis-(μ-4,4'-bipyridine-κN:N')bis-(μ-3-hy-droxy-adamantane-1-carboxyl-ato-κO:O')bis-(3-hy-droxy-adamantane-1-carboxyl-ato-κO)dicobalt(II)] hepta-hydrate].
abstract: The title coordination compound, {[Co(C(11)H(15)O(3))(4)(C(10)H(8)N(2))(2)(H(2)O)]·7H(2)O}(n), consists of a pair of Co(II) atoms, four 3-hy-droxy-adamantane-1-carboxyl-ate anions (L), one water mol-ecule, two bridging 4,4'-bipyridine (4,4'-bpy) ligands and seven uncoordinated water mol-ecules. Both of the Co(II) ions are coordinated in a distorted octa-hedral geometry. Four L ligands bind to each pair of Co(II) atoms in a plane, two of which bridge the two Co(II) atoms as bidentate groups while the other two coordinate to a single Co(II) atom in a monodentate mode. Two half-mol-ecules of 4,4'-bipyridine coordinate the Co(II) atoms from the upside and underside. The packing features extensice O-H⋯O hydrogen bonding.
