Naphthalene-1,8-di­amine–2-(pyrimidin-2-yl)-1H-perimidine (2/1)

In the title adduct, C(15)H(10)N(4)·2C(10)H(10)N(2), the pyrimidine ring is nearly co-planar with the heteroatomic perimidine ring, as indicated dihedral angle between their mean planes of 3.21 (11)°. The di­aminona­phthalene mol­ecules are slightly twisted [dihedral angles = 4.2 (2) and 3.0 (2)°] b...

Sumario:In the title adduct, C(15)H(10)N(4)·2C(10)H(10)N(2), the pyrimidine ring is nearly co-planar with the heteroatomic perimidine ring, as indicated dihedral angle between their mean planes of 3.21 (11)°. The di­aminona­phthalene mol­ecules are slightly twisted [dihedral angles = 4.2 (2) and 3.0 (2)°] because of the steric encumbrance of NH(2) groups. The perimidine and di­aminona­phthalene mol­ecules are linked by N—H⋯N hydrogen bonds, forming an R (4) (4)(12) graph-set motif across an inversion center. In the crystal, alternating layers of the perimidine and di­aminona­phthalene mol­ecules are formed along [100]. In the perimidine layer, mol­ecules are π–π stacked along the c-axis direction with an inter­plane separation of approximately 3.4 Å.
