The aim of this work is to explore the chemistry of new heteroatomic molecular compounds never reported in the scientific literature so far: Ni-P carbonyl clusters. First, an attempt was made to illustrate the reasons which brought to the choice of this specific metal-pnictogen couple, such as the interesting properties of Ni-P binary phases, the difficulties related in obtaining structural data for this bulk compounds and the absence of references about nickel-phosphorus molecular compounds (e.g. carbonyl clusters) reported in literature. Then, the general criteria chosen for the reactions between precursors [Ni6(CO)12]2- and PCl3 or POCl3 have been reported. This work has permitted to individuate many new products, of which some have also been isolated and characterised: [Ni11P(CO)18]3-, [Ni23-xP2(CO)30-x]6- (x=0, 1), [HNi31P4(CO)39]5- e [H2Ni31P4(CO)39]4-. Except for the former, a reproducible synthetic path has been refined for all those new Ni-P carbonyl clusters; furthermore some chemical reactivity has been carried out in order to test their characteristics.
