Descripción
Sumario:The title compound [systematic name: N,N-dieth­yl({[(diethyl­carbamothio­yl)sulfan­yl]selan­yl}sulfan­yl)carbothio­amide], 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 mol­ecules in the asymmetric unit. The Se atoms are tetra­coordinated, 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].
