Synthesis of [C2NH8]2[Co3(HPO3)4] 3
In a typical synthesis,a reaction mixture of Co(CH3-
COO)2$4H2O (3 mmol),CoCl2$ 6H2O (0.75 mmol),piperazine
(5 mmol),H3PO3 (0.9 mL,50% in water) and DMF (20 ml) was
sealed in an Teflon-lined steel autoclave and heated at 120 \3C for
2 d.The resulting blue block crystals were isolated by filtration,
washed with ethanol and dried in air.The agreement between the
experimental and simulated XRD patterns indicated the phase
purity of the product (Fig.S1c†).Analysis found
(%)[C2NH8]2[Co3(HPO3)4]:Co,30.32; P,21.17; C,8.07; H,3.52;
N,4.63.Calc.(%):Co,30.06; P,21.06; C,8.15; H,3.40; N,4.75.
The UV-vis diffuse-reflectance spectrum of 3 exhibits three
absorption maxima at 544,583,and 624 nm (Fig.S2†).The TG
curve of 3 shows a weight loss of 14.28% in the temperature range
of 160–400 \3C,corresponding to the loss of the dimethylamine
molecules (calc.15.62%) (Fig.S3c†).
