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.

abstract  in the wake of renaissance, not only then art and literature pieces but the resulting diverse expressions well reflected the turning revolts in science, philosophy, and politics, and their association which is tremendously clear even among a single artist’s works, e.g. donatello’s sculptures, transparently echoing challenges between old traditions and then new reformations vastly infl...

We show that for every infinite cardinal number m there exist two totally ordered abelian groups whose free product in any nontrivial variety of lattice-ordered groups has a disjoint set of cardinality m. This answers problem 10.7 of [13] and extends the results in [12]. We further prove that for the variety of abelian lattice-ordered groups or the variety of all lattice-ordered groups, the fre...
