ABSTRACT The present invention provides a process for the currentless deposition of electropositive metal layers on to appropriate less electropositive metals by contacting an object to be coated with a coating bath, wherein a coating bath is used which contains a metal complex obtained by reacting a monovalent electropositive metal halide with a base, which is capable of complex formation with the electropositive metal, and a hydrohalic acid. The present invention also provides a coating bath for the currentless deposition of electropositive metal layers on to less electropositive metals, wherein said bath contains an electropositive metal complex obtained by reacting a monovalent electro- positive metal halide with a base which is capable of complex formation with the electropositive metal and a hydrohalic acid. Furthermore, the present invention provides an electropositive metal complex, obtainable by the reaction of a monovalent electropositive metal halide with a base which is capable of complex formation with the electropositive metal and a hydrohalic acid, followed by precipitation from the reaction mixture.
