In the mol-ecule of the title compound, [CdCl(2)(C(24)H(20)N(2))(2)], the Cd(II) centre has a distorted tetra-hedral coordination geometry defined by two chloride ions and two pyridine N atoms of the monodentate 2-[(triphenyl-meth-yl)amino]pyridine ligands. Weak intra-molecular N-H⋯Cl hydrogen bonds help to establish the three-dimensional architecture.

The title compound, [Ag(C(7)H(2)Br(3)O(2))(C(18)H(15)P)(3)], a silver(I) derivative of 3,5,7-tribromo-tropolone, has three triphenyl-phosphine ligands coordinated to the silver centre, whereas the 3,5,7-tribromo-tropolonate anion coordinates as a bidentate ligand. The compound is an example of a five-coordinate silver complex containing a bidentate ligand.

The title compound, (C(21)H(22)P)(2)[Cu(2)I(4)], prepared from reaction between copper powder, iodine and isopropyl triphenyl-phospho-nium iodide in hydroxy-acetone (acetol), shows an already known Cu(2)I(4) (2-) anion with a planar conformation [Cu-I range = 2.5108 (3)-2.5844 (3) Å and I-Cu-I range = 110.821 (10)-125.401 (10)°].

The antibiotic streptozotocin [2-deoxy-2-(3-methyl-3-nitrosoureido)-D-glucopyranoside], an analog of N-acetylglucosamine (NAG), has been shown to be useful for the selection of carbohydrate-negative and auxotrophic bacterial mutants. We have adapted this method for use with the oral pathogen Streptococcus mutans, a gram-positive, aerotolerant anaerobe that uses predominantly carbohydrates as ca...

The asymmetric unit of the title compound, [FeCo(2)(C(5)H(5))(2)(C(3)H(3)S(3))S(C(18)H(15)P)(CO)]CF(3)SO(3), consists of a triangular irondicobalt cluster cation and a trifluoro-methane-sulfonate anion. In the cation, the FeCo(2) triangle is symmetrically capped on one face by an S atom and on the other by a C atom linked to a methyl trithio-carbonate residue that bridges the Fe-C bond. Each Co...

A graphene-based porphyrin molecule (GO-TPP) was synthesized by covalent linkage of graphene oxide (GO) with 5-(4-aminophenyl)-10,15,20-triphenyl porphyrin (TPP-NH2). The yielded graphene-based material is a donor-acceptor (D-A) molecule, exhibiting strong intermolecular interactions between the GO core (A) and the covalently anchored porphyrin molecule (D). To demonstrate the universal role of...

The ligninolytic enzyme system of Phanerochaete chrysosporium decolorizes several recalcitrant dyes. Three isolated lignin peroxidase isoenzymes (LiP 4.65, LiP 4.15, and LiP 3.85) were compared as decolorizers with the crude enzyme system from the culture medium. LiP 4.65 (H2), LiP 4.15 (H7), and LiP 3.85 (H8) were purified by chromatofocusing, and their kinetic parameters were found to be simi...
