	Long-chain metal n-alkanethiolates (MTs) are inorganic-organic hybrid materials, characterized by a metal-sulfur inorganic central plane sandwiched between hydrocarbon bilayers. Though MTs are known for over a century now, their crystal structures are conclusively established only recently. Mixed-metal thiolates (MMTs) are structurally similar to MTs and contain heterometals in the inorganic plane. With a very limited number of MMTs explored to date, their structures remain completely unknown. Here we report the synthesis and structural elucidation of a mixed-metal thiolate, AgBi(SC12H25)4, providing direct insight into heterometal arrangement by combining X-ray absorption fine structure spectroscopy and density functional theory calculations. The results establish that the AgBi MMT contains discrete molecular units like [RS-Ag-SR-Bi(SR)2] containing both Ag and Bi metals with an intramolecular heterometallic mu 2-thiolate bridging. The units further share strong intermolecular Ag \&amp; centerdot;\&amp; centerdot;\&amp; centerdot;Bi metallophilic interactions at a very short distance of 2.72 \&amp; Aring;, playing a crucial role in the self-assembly. Intermolecular metal-to-metal charge transfer occurring both directly and via the thiolate bridge gives rise to the absorption maxima observed in the UV-Vis spectrum. The intermolecular interactions predominantly arise from the thiolate group (RS-) of one unit interacting with the Ag+ and Bi3+ centers of the adjacent units, in addition to the Ag \&amp; centerdot;\&amp; centerdot;\&amp; centerdot;Bi metallophilic interaction.</p>
