ABSTRACT
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 2.2833â
(13)-2.3041â
(15)â
Å] and one weaker bond [range 2.7318â
(14)-2.7873â
(12)â
Å].
