A cobalt(ii) chain based on pymca generated in situ from the hydrolysis of 2-cyanopyrimidine: spin canting and magnetic relaxation

A one-dimensional (1D) coordination polymer, [{Co(2)(pymca)(2)·(H(2)O)(4)}SO(4)·2H(2)O](n) (1) (pymca = 2-carboxypyrimidine), was solvothermally synthesized via the reaction of 2-cyanopyrimidine and Co(SCN)(2). A bidentate pymca ligand was formed in situ by the hydrolysis of 2-cyanopyrimidine. Furth...

Descripción
Sumario:A one-dimensional (1D) coordination polymer, [{Co(2)(pymca)(2)·(H(2)O)(4)}SO(4)·2H(2)O](n) (1) (pymca = 2-carboxypyrimidine), was solvothermally synthesized via the reaction of 2-cyanopyrimidine and Co(SCN)(2). A bidentate pymca ligand was formed in situ by the hydrolysis of 2-cyanopyrimidine. Furthermore, in this study, the magnetic properties of complex 1 were investigated in detail. The results indicated that complex 1 showed a single-chain magnet (SCM) behavior below ca. 3 K. The energy barrier (Δτ(1)/k(B)) and preexponential factor (τ(0)) of SCM were 31.2 K and 5.4 × 10(−9) s, respectively.
