I can label groups in a bar chart but when trying to rotate the column labels I get unexpected results.

This works:

BarChart[{{1, 2, 3}, {4, 5, 6}}, 
 ChartLabels -> {{"c1", "c2"}, {"r1", "r2", "r3"}}]

this doesn't:

BarChart[{{1, 2, 3}, {4, 5, 6}}, 
 ChartLabels -> 
  Placed[{{"c1", "c2"}, {"r1", "r2", "r3"}}, Axis, Rotate[#, Pi/4] &]]

What am I doing wring?

Placed should be inside the List:

BarChart[{{1, 2, 3}, {4, 5, 6}}, 
  ChartLabels -> {Placed[{"c1", "c2"}, Axis, Rotate[#, Pi/4] &], 
    Placed[{"r1", "r2", "r3"}, Axis, Rotate[#, Pi/4] &]}]
