چکیده
A second monoclinic polymorph of the title mol-ecule, C(15)H(21)FN(3)O(4)P, is reported in the space group P2(1)/n and compared to the previously reported C2/c space group [Gholivand et al. (2006 ▶). Polyhedron, 25, 711-721]. The asymmetric unit of the title compound consists of two independent mol-ecules. The P atoms adopt a distorted tetra-hedral environment. In the C(O)NHP(O) fragment, the P=O and the N-H groups are in a syn conformation with respect to each other and in the crystal, inter-molecular N-H⋯O=P hydrogen bonds form dimeric aggregates.

The title compound, C(15)H(14)N(4)O(2)S, is a derivative of thio-ureadihydrazide. In contrast to the previously reported polymorph (ortho-rhom-bic, space group Pbca, Z = 8), the current study revealed monoclinic symmetry (space group P2(1)/n, Z = 4). The mol-ecule shows non-crystallographic C(2) as well as approximate C(s) symmetry. Intra-molecular bifurcated O-H⋯(N,S) hydrogen bonds, are prese...
