THE TITLE COMPOUND [SYSTEMATIC NAME: N,N-dieth-yl({[(diethyl-carbamothio-yl)sulfan-yl]selan-yl}sulfan-yl)carbothio-amide], C(10)H(20)N(2)S(4)Se, crystallizes in a new form in the space group Pca2(1): the previously reported polymorph crystallizes in the space group P2(1)2(1)2(1). The new phase contains two independent mol-ecules in the asymmetric unit. The Se atoms are tetra-coordinated, with a distorted square-planar geometry. The ligands coordinate asymmetrically to the Se atoms, with one strong Se-S bond [range 2.2833 (13)-2.3041 (15) Å] and one weaker bond [range 2.7318 (14)-2.7873 (12) Å].
标题化合物[系统名称：N,N-二乙基({[(二乙基氨基硫甲酰基)硫烷基]硒烷基}硫烷基)硫代甲酰胺]，C(10)H(20)N(2)S(4)Se，以新的晶型在空间群Pca2(1)中结晶：先前报道的多晶型物在空间群P2(1)2(1)2(1)中结晶。新相在不对称单元中包含两个独立的分子。硒原子为四配位，具有扭曲的平面正方形几何构型。配体以不对称方式与硒原子配位，有一个强的硒-硫键[范围为2.2833 (13)-2.3041 (15) Å]和一个较弱的键[范围为2.7318 (14)-2.7873 (12) Å]。
