CCDC no.: 1852427

The crystal structure is shown in the figure. Tables 1 and 2 contain details on crystal structure and measurement conditions and a list of the atoms including atomic coordinates and displacement parameters.

Source of material

A mixture of naphthalene-1,8-diamine (1.58 g, 10 mmol) and 4-bromobenzaldehyde (1.85 g, 10 mmol), in anhydrous ethanol (50 mL) was refluxed at 353 K for about 2 h. Then the solvent was removed under reduced presure. The resulting residue was purified by recrystallization from ethanol to obtain a crystal (yield 2.86 g, 88%).

Experimental details

All hydrogen atoms were identified in difference Fourier syntheses. The Uiso values of the hydrogen atoms were set to 1.2 Ueq(C).

Comment

Perimidines have drawn extensive examinations of many researchers for a long time, because they exhibit a diverse range of biological activities [1], [2], [3]. There are several preparative methods for the synthesis of perimidine derivatives [4], [5], [6], [7]. Herein, we report on a novel perimidine compound which was synthesized and characterized by single-crystal X-ray diffraction.

In the structure, the bond angles of N(1)—C(11)—N(2), N(1)—C(11)—C(12) and N(2)—C(11)—C(12) are 107.17(19), 109.31(19) and 113.3(2) in turn, which indicates the sp3 hybridization state of C(11) atom and the new-formed three-membered heterocyclic ring is nonplanar. All bond lengths and angles are in the expected ranges [8].
