[Tex/LaTex] Undefined Control Sequence in bibtex

bibliographiesbibtex

I do not understand why my bibliography is not showing: I ran a very simple file to test it and I get the same error as in my main file.

\documentstyle{amsart}
\begin{document}
\nocite{*}
\bibliographystyle{amsplain}
\bibliography{C:\Users\...\References}
\end{document}

I get on line 5 (\bibliography)

! Undefined control sequence.<write> \string \bibdata {C:\Users\...\Bibliography ... ...rdo\...\References} 

I am running the correct sequence on TeXMaker to get the bibliography and I even did get an output on other files. the bibtex file is not in the same folder as the script, but there is no difference when they are together.
What is wrong?

EDIT

 \documentclass{article}

 \begin{document}
 \cite{Franceschini.2008}
 \bibliographystyle{amsplain}
 \bibliography{C:/Users/.../References}
 \end{document}

\Users is an undefined command. Use / as the path separator.
