Abstract

Hydrothermal reactions of MoO3, an appropriate metal salt, an imine ligand, an organoarsonic acid, and an acid mineralizer yielded a series of compounds of the M(II)-imine/MoxOy/RAsO3 2- family. Under the low temperature conditions of this study, molecular species predominated as illustrated by the isolated hexamolybdoarsonate clusters of (H2bpy′)2[Mo 6O18(O3AsC6H5) 2]·4H2O (1·4H2O) and [Co(phen)3][Mo6O17(OH)(H2O) (O 3AsC6H5)2]·4H2O (2·4H2O) and the secondary metal decorated clusters [{M(bpy)2}Mo6O18(O3AsC 6H4NH2)2] (M = Co(3), Ni(4), Zn(5) and [{Cu(dpyra)(H2O)}2Mo6O18(O 3AsC6H5)2] (6) and the dodecamolybdoarsonate cluster (Hdpyra)2[{Cu(dpyra)(H 2O)2}Mo12O34(O3AsC 6H5)4]·6H2O (7·6H 2O). The only extended structure is provided by the two-dimensional phase [{Cu(bpy)(H2O)}2Mo6O18(O 3AsC6H4NH2)2] ·3H2O (8·3H2O) (bpy = 2,2′-bipyridine, phen = o-phenanthroline, dpyra = dipyridylamine, bpy′ = 4,4′-bipyridine).
