problem in alignment of arrays

Question

\documentclass[12pt]{report}
\usepackage{amsfonts,amsmath,mathtools}
\begin{document}
\begin{align*}
0\longrightarrow S
\xrightarrow{
\begin{array}{c}
xyz\\
\end{array}
\left[\begin{array}{rrr}
1 \\-1 \\1 \\
\end{array}
 \right]
 \begin{matrix}
\\yz\\xz\\xy
 \end{matrix}
}S^3
\xrightarrow{
\begin{array}{rrr}
yz&xz&xy\\
\left[\begin{array}{rrr}
0&1&1\\
1&0&-1\\
-1&-1&0\\
\end{array}
\right]
\end{array}
}S^3
\end{align*}
\end{document}

I want to align the row yz xz xy with the top row of the 3 by 3 matrix given in the code

There is at least one \end{array} missing. At least your code does not compile. Please try to give us compilable code and to give more information on what you want to achieve and what you have tried so far. — LaRiFaRi, Nov 18 '16 at 10:51
But know I can see what you have been talking about. You could minimize your code a lot to the actual problem. The solution to your problem is: http://tex.stackexchange.com/q/59517 or http://tex.stackexchange.com/q/223501 or http://tex.stackexchange.com/q/46722 or http://tex.stackexchange.com/q/30791 — LaRiFaRi, Nov 18 '16 at 11:24

Maybe you want something like this?

\documentclass[12pt]{report}
\usepackage{amsfonts, mathtools}

\begin{document}

\begin{align*}
  0 ―――→ S
  \xrightarrow{
  xyz
  \begin{bsmallmatrix*}[r]
  1 \\-1 \\1
  \end{bsmallmatrix*}
  \begin{smallmatrix}
  yz\\xz\\xy
  \end{smallmatrix}%
  }S³
  \xrightarrow{
  \begin{matrix}
  \begin{smallmatrix*}
    & yz & & zx & & xy \end{smallmatrix*} \\
  \begin{bsmallmatrix*}[r]
  0&1&1\\
  1&0&-1\\
  -1&-1&0\\
  \end{bsmallmatrix*}
  \end{matrix}
  }S³
\end{align*}

\end{document}
