Abstract:
In the title compound, C(13)H(10)S(2)Te, the dibenzothio-phene moiety is almost planar, the maximum atomic deviation being 0.055 (5) Å. The two Te-C bonds are nearly perpen-dicular to each other with a C-Te-C bond angle of 93.0 (2)°. An inter-molecular C-H⋯π inter-action is present between the methyl-ene group and thio-phene ring.Keywords:

The skeletal structure of azalomycin F4a (1) was determined on the basis of available data about the physicochemical properties of F4a and about the structures of the degradation products of this compound and of its derivatives. The structure was found to consist of a 36-membered lactone ring bearing multiple hydroxy functions, a diene and a dienoic ester group, as well as a side chain with an N-methylguanidine moiety as its terminal. One of the hydroxyl groups on the lactone ring forms a hemiketal ring with the keto group on a ring carbon, and another hydroxyl group forms a hemiester with a malonic acid moiety.

In the title compound, C(16)H(18)N(2)O(4)S, the dihedral angle between the hy-droxy-phenyl ring and the plane of the thio-urea moiety is 54.53 (8)°. The H atoms of the NH groups of thio-urea are positioned anti to each other. In the crystal, inter-molecular N-H⋯S, N-H⋯O, and O-H⋯S hydrogen bonds link the mol-ecules into a three-dimensional network.

In the title compound, C(19)H(14)OS, the naphtho-thio-phene moiety is almost planar except for the S atom of the five-membered ring, which is situated 0.047 (6) Å out of the C(4) plane (with an r.m.s. deviation of fitted atoms = 0.0009 Å). The dihedral angle between the naphtho-thio-phene plane and the attached meth-oxy-phenyl ring is 67.6 (2)°. In the crystal, a C-H⋯π inter-action is observed between a meth-oxy-phenyl C-H group and the outer benzene ring of the naphtho-thio-phene moiety. The five-membered ring of the naphtho-thio-phene moiety is disordered, with the S and opposite non-fused C atom approximately exchanging positions, with a site-occupancy factors of 0.808 (3) and 0.187 (3).
