Description of two Stenohya species from China (Pseudoscorpiones, Neobisiidae), with comments on the exaggerated sexual dimorphic pedipalp in this genus.

Two Stenohya species belonging to the family Neobisiidae are diagnosed, described, and illustrated from China: Stenohyaspinatasp. nov. from Chongqing Municipality, and Stenohyahuangi Hu & Zhang, 2012 from Fujian Province. The male of S.huangi is reported for the first time. Diagnostic characters of this species are restricted based on the holotype and the new specimens. In addition, a key and a distribution map of the Stenohya species from China are provided, and the potential function of the exaggerated sexual dimorphic pedipalp in the genus Stenohya is discussed.

Iron(II) Bis(imidazole) Derivatives of a Binuclear Porphyrin Model: Crystal Structures and Mössbauer Properties.

A new sterically hindered "picket fence-like" porphyrin with chelates for the second metal atom, H2TImPP (TImPP = meso-tetrakis[α,α,α,α-o-(5-imidazolecarboxylaminophenyl)]porphyrinato), is developed and used in the synthesis of four iron(II) bis(imidazole) derivatives, which are characterized by single crystal X-ray and other spectroscopies. The comprehensive studies on the crystal structures revealed noteworthy features including new axial ligand arrangements, deformed porphyrin planes, and strongly tilted pickets which can be rationalized by analysis of the intra- and intermolecular interactions. Solid-state Mössbauer experiments on [Fe(TImPP)(1-MeIm)2] were conducted at several temperatures from 295 to 25 K. The quadrupole splitting (ΔEQ) in the range of 1.01-1.03 mm/s confirmed the low-spin state of the iron.
