SYNTHESIS AND SYNCHROTRON MICROCRYSTAL STRUCTURE OF AN ALUMINOPHOSPHATE WITH CHIRAL LAYERS CONTAINING LAMBDA-TRIS(ETHYLENEDIAMINE)COBALT(III)

A chiral aluminophosphate, d-Co(en)(3).Al3P4O16.3H(2)O, has been synth esized using optically pure d-Co(en)(3)(3+) as a templating agent (en = 1,2-diaminoethane). The structure of the material has been determine d from a small single crystal using synchrotron radiation and imaging plate detection. The aluminophosphate contains chiral macroanionic she ets similar to those previously reported in trans-Co(dien)(2).Al3P4O16 .xH(2)O (dien = diethylenetriamine).
