Invoke remote diskpart with pipe results in 'C:\windows\system32\diskpart.exe}' is not recognized as an internal or external command

Question

Hi,
 I am trying to invoke commands from powershell(resp. the code below is run from CMD, because it should be part of CMD script in future), especially the diskpart and do some operations.
I am trying to use this:
"C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe" Invoke-Command -ComputerName "machinename" -ScriptBlock {"select disk 2", "online disk" | diskpart}
but keep getting this:
'diskpart.exe}' is not recognized as an internal or external command...
I also tried with full path to diskpart but I get this:
'C:\windows\system32\diskpart.exe}' is not recognized as an internal or external command...
can you help me with that? I would use powershell directly but the system is Server 2008 R2 where storage modules are not present..
execution policy is set to unrestricted
I should also note, that SYSTEM32 where diskpart resides IS part of variables on both systems
Thank you.

Hi, 
 thanks for answer. It works as you say but I am calling powershell from within CMD (cmd script), its the reason, why this:
"C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe" 
is being included. And that is not working.
