By
using an achiral (4-carboxynaphthalen-1-yl)phosphonic acid (4-cnappH3), compound Co2(4-cnapp)(OH)(H2O)2 (1) is isolated crystallizing in orthorhomibic
space group P212121. It shows a three-dimensional framework structure in which the Δ-type
chains of corner-sharing Co3(μ3-OH) triangles
are cross-linked by the organic groups of the phosphonate ligands.
Interestingly, the bulk sample of compound 1 is enantioenriched,
thus providing a rare example of symmetry breaking upon crystallization
from achiral starting materials. Slow magnetization relaxation is
observed at low temperature.
