A new organic–inorganic hybrid, [Pb2I4(C4H13N3)]n, was obtained by the reaction of C4N3H10 and PbI2 at room temperature. The structure is a three-dimensional polymer resulting from the association of PbI6 octa­hedra and a mixed lead organic–inorganic PbI4(C4N3H13) coordination polyhedron. Both Pb atoms, two I atoms and one N atom lie on a mirror plane. N—H⋯I hydrogen bonds further connect the organic unit and some I atoms.

This paper presents an idea of automatic generation of SoC architecture from a functional specification. Starting from an application task graph, C code will be generated automatically. Then the user can add the specific code of each task. Compilation rules are used in order to have a correct task graph and c code. Finally, an automatic generation of hardware and software SoC architecture will be down to get a new model prototype of the FPGA based SOC platform. We demonstrate the effectiveness of the proposed idea by the implementation of CAGT software tool which can generate efficient and correct C code from a task graph. The generated code is compliant to the ANSI C standard thus can be accepted by most compilers.
