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.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
