Russian oligarch Oleg Deripaska’s U.S.-based assets are currently frozen, including an Upper East Side mansion with a history. According to the New York Post Deripaska first purchased the posh residence for $42.5 million back in 2008, but recent battles between him and the U.S. government have suspended his access to the home, which sits just down the street from fellow Ukranian-born oligarch Len Blavatnik’s mansion. (Blavatnik bought the home for a record-setting $90 million earlier this year.) The point of contention here is that Deripaska is believed to be linked to both Russian mob leaders and Russian President Vladimir Putin; he is on the sanctions list for those connections as well as for his alleged involvement in crimes including murder, money-laundering, bribery, and racketeering. Additionally, Deripaska happened to have Trump’s ex-campaign manager Paul Manafort on his payroll for years. Not to be deterred, however, Deripaska has made an interesting move, arranging to have his business partner, oligarch Roman Abramovich, move his children and ex-wife Dasha Zhukova into the seized home, a double-wide, five-story townhouse.

Earlier this year, Abramovich made headlines when he pushed ahead with plans to build a mega-mansion on the upper east side, and then later revealed that the historic multi-townhouse home would actually be for Zhukova and not for himself. The home, which will combine three townhouses, will be “the biggest home the city has ever seen,” according to a rep for Stephen Wang, the architect who will engineer the mega-mansion. In all, he has transferred $92 million worth of property to Zhukova this year, who, it is worth noting, is close friends with Ivanka Trump. And to add one more complication to the situation, Abramovich is currently dating Deripzska’s estranged wife, Polina Derispaska.
