Synthesis and crystal structure of poly[[bis-(aqua-κO)tetra-kis-(μ-4,4'-bi-pyridine-κ2 N:N')hexa-kis-(3-chloro-benzoato)-κ5 O;κ2 O:O'-tricobalt(II)] methanol disolvate].

ABSTRACT: A novel ladder-chain cobalt(II) coordination polymer, {[Co3(C7H4ClO2)6(C10H8N2)4(H2O)2]·2CH3OH} n , was synthesized and characterized. The structure contains two CoII centres with different octa-hedral environments, [Co(1)N3O3] and [Co(2)N2O4]. The O-donating 3-chloro-benzoate anions (3-Clbenz) act as the terminal ligands, while the N-donating 4,4'-bipy mol-ecules play the role of linkers. The Co(1) ions are linked by 4,4'-bipy mol-ecules into linear chains. Two such chains are joined by [Co(2)(3-Clbenz)2(H2O)2] units via two 4,4'-bipy bridging ligands, thus forming the ladder-chain structure. The crystal packing of the title compound is stabilized by supra-molecular inter-actions, such as hydrogen bonding, π-π and halogen⋯π contacts, giving a three-dimensional framework. The spectroscopic and thermal properties of the title compound have also been investigated.
