A Russian billionaire’s planned $75 million, record-breaking purchase of a Fifth Avenue co-op is in limbo — because the owner’s wealthy widow is convinced she can get even more dough from the oligarch, sources told The Post.
Heiress Angelika Ivanc has told confidants that businessman Roman Abramovich was set to pony up even more dough for the historic, 22-room home she shared with her late husband, real-estate titan Howard Ronson, before trustees for Ronson’s estate took the offer, the sources said.
Now the stunning blonde has no intention of moving out of the ultra-posh digs, a source said.
Abramovich’s offer for the Ronson’s home at 828 Fifth Ave., off East 65th Street, home would shatter the record for Manhattan’s most expensive co-op sale, held by David Geffen’s $54 million purchase of Denise Rich’s former pad at 785 Fifth Ave.
Abramovich and his baby mama, Dasha Zhukova, had signed a contract with executors of Howard Ronson’s estate and were supposed to close in December.
“[Angelika] is out of her mind,” said a source. “It was a very fair deal.”
Ivanc is challenging the executors’ approval of the co-op sale in court in the English Channel island of Guernsey, where Ronson’s company had offices.
While a European court ruling would not bar the sale in New York, legal experts say that the controversy would likely be enough to force the parties to hold off on the transaction until the court case is resolved.
The co-op is part of the Berwind Mansion, built by a coal baron.
Howard Ronson had dreamed of restoring the home to a single-family mansion, but failed to buy out the other tenants. After he died in 2007, his estate he put the co-op on the market for $72 million.
Abramovich also wants to convert the property to a single-family manse.
He has so far managed to buy the unit owned by designer Adolfo Sardina — Nancy Reagan’s favorite designer — but hasn’t been able to budge the mansion’s other wealthy tenant, Eugenia de Olazabal, sources said.
As Ivanc left the mansion on Monday, swathed in black mink and teetering on black-and-silver spike heels, she told a Post reporter that she was on her way to the “cinema” and could not talk.
She grabbed her two little girls — also sporting knee-length fur coats — by the hand and hopped into a waiting SUV.
Reps at Howard Ronson’s US-based company didn’t return calls.
