Charlton plc chairman Derek Chappell, club president Sir Maurice Hatter and Murray are among the people who have ploughed more money into the club.
Murray will also replace Chappell as chairman of the plc board.
“I am delighted that once again the key funders of the business have stepped forward to resolve the club’s immediate financial requirements, and everyone involved deserves enormous credit,” Murray told the club’s official website.
“I am delighted to accept the plc board’s invitation to become plc chairman, and I would like to thank Derek for all his work as plc chairman since he took on the role in January 2008 and for his support at this time.”
Chappell added: “We have been working extremely hard in recent months to attract new investment into the club, and indeed have made progress with a number of interested parties only for that interest to fail to result in any tangible benefit. Attracting new investment into the club continues to be our primary objective.
“I hope that by retaining our key players, and indeed adding to the squad during the recent transfer window, we have once again demonstrated our commitment to the club, both as supporters and investors.
“After such an outstanding start to the season, it was essential that we brought stability to the club’s finances and removed the need for player sales, and the action we have taken will achieve both objectives and hopefully provide the platform for us to make an immediate return to the Championship.”
