Abstract

The compounds Co₂(OH)(5-cnapp)(H₂O) (1) and Co₈(OH)(4-cnapp)₅(H₂O)₁₀·12H₂O (2) obtained using positionally isomeric phosphonic acids (5-/4-cnappH₃) have 3D framework structures. Compound 1 contains a distorted Co₃(μ₃-OH)-based kagomé layer and shows long-range weak ferromagnetic ordering below 30 K without significant spin frustration.
