The heats of solution of silver and gold in dilute Ag-Au-Sn alloys have been determined as a function of alloy composition using liquid metal solution calorimetry. From the values obtained, the various enthalpy interaction parameters in the liquid solutions have been calculated. The results are interpreted in terms of the probably bonding changes taking place between silver, gold and tin atoms.

Au2AgSn crystallizes in the orthorhombic Immm space group. The structure is one-dimensional and consists of two Au2AgSn ribbons oriented in the (1, 0, 0) direction. Au is bonded in a linear geometry to one Ag and one Sn atom. The Au–Ag bond length is 2.65 Å. The Au–Sn bond length is 2.59 Å. Ag is bonded in a linear geometry to two equivalent Au atoms. Sn is bonded in a linear geometry to two equivalent Au atoms.
