Palladium(II) complexes of thiones having the general formula [Pd(L) 4 ]Cl 2 , where L = thiourea (Tu), methylthiourea (Metu), N,N 0 -dimethylthiourea (Dmtu), and tetramethylthiourea (Tmtu) were prepared by reacting K 2 [PdCl 4 ] with the corresponding thiones. The complexes have been characterized by elemental analysis, IR and NMR spectroscopy, and two of these, [Pd(Dmtu) 4 ]Cl 2 Á 2H 2 O (1) and [Pd(Tmtu) 4 ]Cl 2 (2), by X-ray crystallography. An upfield shift in the[C=S resonance of thiones in 13 C NMR and downfield shift in N-H resonance in 1 H NMR are consistent in showing sulfur coordination with palladium(II). The crystal structures of the complexes show a square-planar coordination environment around the Pd(II) ions with the average cis and trans S-Pd-S bond angles of 89.64°and 173.48°, respectively.

The title compound, [Pd(CH4N2S)4](SCN)2, consists of complex [Pd(TU)4]2+ [TU = thiourea, SC(NH2)2] cations and thiocyanate counter-anions. The PdII cation is situated on an inversion centre and exhibits an almost square-planar coordination by the S atoms of the TU ligands. The complex cations are connected through the thiocyanate ions via N—H⋯N [2.922 (3)–3.056 (3) Å] and N—H⋯S [3.369 (2)–3.645 (2) Å] hydrogen bonds.
Karakoram mountain range contains the tallest mountain peaks of the world with thousands of glaciers which are microbiologically untapped. This is a pioneer approach of isolation and characterization of fungi from Batura glacier, Karakoram, Pakistan. Total number (CFU/mL or g) was determined at 4 °C and 15 °C to isolate psychrophilic and psychrotrophic fungi, respectively. About 33 different fungi were isolated from sediment (29), ice (2) and water (2) and were identified morphologically and by sequencing of specific internal transcribed spacer region of the species through internal transcribed spacer 1 (ITS1) and internal transcribed spacer 2 (ITS2) primers. Mostly, the fungal isolates belonged to genus Penicillium, followed by Cladosporium,
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
