AB  - Recrystallization of the title compound, [Fe(C5H5)(C14H13N2O3)], from a mixture of n-hexane and dichloromethane gave the new polymorph, denoted (I), which crystallizes in the same space group (P (1) over bar) as the previously reported structure, denoted (II). The Fe-C distances in (I) range from 2.015 (3) to 2.048 (2) angstrom and the average value of the C-C bond lengths in the two cyclopentadienyl (Cp) rings is 1.403 (13) angstrom. As indicated by the smallest C-Cg1-Cg2-C torsion angle of 1.4 degrees (Cg1 and Cg2 are the centroids of the two Cp rings), the orientation of the Cp rings in (I) is more eclipsed than in the case of (II), for which the value was 15.3 degrees. Despite the pronounced conformational similarity between (I) and (II), the formation of self-complementary N-H center dot center dot center dot O hydrogen-bonded dimers represents the only structural motif common to the two polymorphs. In the extended structure, molecules of (I) utilize C-H center dot center dot center dot O hydrogen bonds and, unlike (II), an extensive set of intermolecular C-H center dot center dot center dot pi interactions. Finger-print plots based on Hirshfeld surfaces are used to compare the packing of the two polymorphs.

AB  - The article describes the synthesis and crystal structure of the Mn(II) complex with 2,6-diacetylpyridine bis (Girard-T hydrazone), (H(2)dap(GT)(2))(2+), of the formula [Mn(H(2)dap(GT)(2))(NCS)(2)](NCS)(2)center dot MeOH. The complex has a pentagonal-bipyramidal coordination geometry, with pentadentate N(3)O(2) ligand in the equatorial plane and two isothiocyanato groups in the axial positions. Both the ligand and the complex are characterized by their FT-IR spectra and thermal data. (C) 2010 Elsevier B.V. All rights reserved.
