Money is an attraction ensnaring Charlie (5)
I believe the answer is:
lucre
'money' is the definition.
(lucre is a kind of money)
'an attraction ensnaring charlie' is the wordplay.
'an attraction' becomes 'lure' (lure is a kind of attraction).
'ensnaring' means one lot of letters goes inside another.
'charlie' becomes 'c' (phonetic alphabet: alpha, bravo, charlie etc.).
'lure' enclosing 'c' is 'LUCRE'.
'is' is the link.
(Other definitions for lucre that I've seen before include "Possession of the rich" , "(Filthy) profit" , "Ill-gotten riches" , "Money or wealth" , "Cruel kind of money, may be filthy" .)
