Diethyl 3-amino-4-[(triphenyl-phosphor-anyl-idene)amino]thieno[2,3-b]thio-phene-2,5-dicarboxyl-ate.

ABSTRACT: The asymmetric unit of the title compound, C(30)H(27)N(2)O(4)PS(2), consists of two crystallographically independent mol-ecules. The thieno[2,3-b]thio-phene ring systems are planar. One of the terminal ethyl groups is disordered over two positions; the site occupancy factors are ca 0.7 and 0.3. The crystal structure is stabilized by N-H?N, N-H?O and C-H?O hydrogen bonds.

The asymmetric unit of the title compound, C(30)H(27)N(2)O(4)PS(2), consists of two crystallographically independent mol-ecules. The thieno[2,3-b]thio-phene ring systems are planar. One of the terminal ethyl groups is disordered over two positions; the site occupancy factors are ca 0.7 and 0.3. The crystal structure is stabilized by N-H⋯N, N-H⋯O and C-H⋯O hydrogen bonds. ...[more]
