rename files with powershell by deleting everything after the @ mark in the filename

I have files named like 12420025@pa20s6gz@12420025_xxxgggopppxk.pdf

I want to rename them so that everything after the @ mark until the . and file extension are removed. So it would look like 12420025.pdf I tried this but it gives an error. I cd'd to the directory in powershell and tried

Get-ChildItem -Filter *.pdf | Foreach-Object -Process {       $NewName = [Regex]::Match($@.Name,"^[^@]*").Value + '.pdf'      $@ | Rename-Item -NewName $NewName  

but I am getting this error

At line:2 char:31  +     $NewName = [Regex]::Match($@.Name,"^[^@]*").Value + '.pdf'  +                               ~  Missing ')' in method call.  At line:2 char:31  +     $NewName = [Regex]::Match($@.Name,"^[^@]*").Value + '.pdf'  +                               ~~~~~~~  Unexpected token '$@.Name' in expression or statement.
