A Two-Fold Interpenetrated Coordination Framework with a Rare (3,6)-Connected loh1 Topology: Magnetic Properties and Photocatalytic Behavior

A new manganese(II) coordination polymer, [Mn-2(L1)(4/3)(L2)(2)](n) (1) (L1 = 4'-(4-pyridyl)-4,2':6',4 ''-terpyridine, H(2)L2 = (4-phenyl)-2,6-bis(4-carboxyphenyl)pyridine), has been prepared and structurally characterized. Complex 1 is a 2-fold interpenetrated three-dimensional framework, which to our knowledge represents the first interpenetration example of coordination framework with unique (3,6) connected loh1 topology. Furthermore, the magnetic properties and photocatalytic activity have been investigated. As a result, complex 1 displays a weak antiferromagnetic interaction among the Mn(II) centers and good photocatalytic activity for the degradation of methyl orange solution under ultraviolet light irradiation.
