A　one-dimensional　solid　and　a　two-dimensional　solid　consisting　of　polyoxoanions　bridged　by　{CoO3N2}　and　{CoO4}　groups　respectively　have　been　synthesized　by　the　hydrothermal　method　and　structurally　characterized　by　X-ray　crystallography.　Each　structure　has　the　[(PO4)4　Mo6O15]12-　cluster　that　is　commonly　observed　in　many　molybdophosphates.　In　compound　1.　[(PO4)4　Mo6O15]l2-　clusters　are　linked　by　{CoO3N2}　groups　to　form　a　chain-like　structure,　and　the　chains　are　hydrogen-bonded　into　a　network.　Compound　2　is　a　layer　structure　with　channels　constructed　from　[(PO4)4　Mo6O15]12-　clusters　and　{CoO4}　groups,　the　organic　molecules　and　the　lattice　water　molecules　are　distributed　disorderly　in　the　interlamellar　region　and　form　strong　hydrogen　bonds　with　inorganic　framework.　The　IR　and　the　fluorescent　spectra　were　investigated　and　discussed.
