7,11-Bis(4-methyl­phen­yl)-2,4,8,10-tetra­azaspiro­[5.5]undecane-1,3,5,9-tetra­one

In the mol­ecule of the title compound, C(21)H(20)N(4)O(4), the two methyl­phenyl rings are oriented at a dihedral angle of 59.32 (4)°. The other two rings have flattened-boat conformations. In the crystal structure, inter­molecular N—H⋯O hydrogen bonds link the mol­ecules. There are C—H⋯π contacts...

Sumario:In the mol­ecule of the title compound, C(21)H(20)N(4)O(4), the two methyl­phenyl rings are oriented at a dihedral angle of 59.32 (4)°. The other two rings have flattened-boat conformations. In the crystal structure, inter­molecular N—H⋯O hydrogen bonds link the mol­ecules. There are C—H⋯π contacts between a methyl­phenyl ring and methyl and methine groups.
