Synthesis and crystal structure of a layered cobalt phosphate with a racemic 1,2-Diaminopropane template

A novel layered cobalt phosphate with racemic 1,2-diaminopropane as the templating agent, [CH₂(NH₃)-CH(NH₃)CH₃] [CoPO₄]₂, has been synthesized and structurally characterized by single-crystal X-ray diffraction methods. The compound crystallizes in the monoclinic system, space group P2₁/c with a = 10.457(2), b = 7.849(1), c = 6.692(l)?Å, β = 103.30(1)°, V = 534.5(2)?ų, Z = 2. The interaction of cobalt phosphate anionic layers and doubly protonated 1,2-diaminopropane cations is mainly ionic. The crystal structure is stabilized by a hydrogen bonding network between layers and templating cations.
