A rare example of a microporous metal-organic phosphate, [Co-12(L)(6)(mu(3)-PO4)(4)(mu(3)-F)(4)(mu-H2O)(6)][NO3](2) (1), is synthesized by the reaction of a [(eta(5)-C5H5)Fe-II](+)-functionalized terephthalate ligand with Co(NO3)(2)center dot 6H(2)O and phosphate and fluoride ions generated from the in situ hydrolysis of hexafluorophosphate. 1 is a cubic, 12-connected, face-centered cubic framework sustained by the linear connection of unprecedented, dodecanuclear truncated tetrahedral coordination clusters.
