Incorporation of robotic automation to chemical synthesis and discovery llows a more rapid, efficient and reliable investigation of the chemical space nvolved, compared to a manual approach, whilst simultaneously allowing the ncorporation of inline analytics for automated real-time monitoring and recording of experimental progress. The objective of this thesis was to create a robot capable of liquid handling and inline analytics, and use these capabilities in two regards: firstly, to generate random numbers by observing outcomes of the random processes in compound synthesis and crystallisation, and secondly to discover new large iron-oxo clusters. This thesis presents the development and results of using robotic automation and analysis in two areas. In the first, a robotic synthesis platform was used to investigate the stochasticity involved in chemical synthesis and crystallisation of polyoxometalates and coordination clusters by using observations of crystallisations to generate random numbers. In the second, a combination of a robotic synthesis platform and traditional bench methods were used to discover large iron oxide clusters. Chapter one provides an overview of the fields studied in this thesis, beginning with an overview of polyoxometalate chemistry as an archetypal example of large molecular metal oxides. This is followed by current state of the art in large ironoxide cluster chemistry and synthetic approaches to compound discovery. Chapter one then concludes by discussing current approaches to automation of chemistry. Chapter two then describes the construction of a platform for automation and visual analysis of inorganic chemical synthesis and crystallisation while chapter three presents the approached used in, and results from this platform in using synthesis and crystallisation of chemical compounds to true generate random numbers. In chapter four, the discovery and characterisation of new large iron oxide compounds is presented from both automated and traditional bench methods, including the double stranded ring {Fe16}, and the large aggregates of {Fe30}, {Fe34} and {Fe36}.
