The crystal of DPCP-ETSC belongs to the orthorhombic system, space group Pna21, and its lattice parameters are as follows: a=1.1478 (2) nm, b=1.3545 (2) nm, c=1.1994 (2) nm, V=l.8646 (4) nm^3, Z=4, Dc=1.345 g/cm^3,μ=0.194 mm^(-1), F (000)=792, R=0.0345, wR=0.0694. The intermolecular hydrogen bonds led to the formation of chain-like one-dimensional compound along c axis and extended along ab plane to form the wave-like supramolecular structure.

DPCP-ETSC晶体属于正交晶系，Pna21空间群，晶胞参数：a=1.1478(2)nm，b=1.3545(2)nm，c=1.1994(2)nm，V=1.5646(4)nm^3，Z=4，D=1.3459/立方公分，μ=0.194mm^(-1)，F(000)=792，R=0.0345，wR=0.0694，此化合物通过分子间氢键形成沿c轴成链状，沿ab平面成波浪状的超分子结构。
