Innovative Phone-in Radio Program for Prisoners Enrolled as Students at Indira Gandhi National Open University

Providing education to prisoners while in jail is a win-win situation for both prisoners and society. For prisoners, the educational experiences in jail reduce their mental strain, isolation, and stress due to incarceration and simultaneously make them employment ready after their release from prison. Education helps prisoners become fit to earn on their own, and thereby reduces the chances of returning to jail (recidivism). Therefore, through educational experiences, the government saves money on prisoners\u27 maintenance and earns taxes from their later employment. Providing education to prisoners, especially increasing efforts to provide quality education, such as is available to common students, is needed. The ‘Nagpur Experiment’, wherein the student prisoners of Indira Gandhi National Open University (IGNOU) at Nagpur Central Jail are provided the‘Mediated Phone in Radio Counselling’ through public radio on a live radio programme is an attempt in this direction

Metallorganische Lewis-Säuren. L

Die Metallorganischen Lewis-Säuren Ph3PAuNO3 (1) und (CO)5ReFBF3 (2) setzen sich mit den Dithiolato-Metallkomplexen (Bu4N)2[M(mnt)2] (mnt = maleonitrildithiolato, M = Ni, Cu, Pt, Zn) und (Bu4N)2[Zn(dmit)2] (dmit = dimercaptoisotrithiono) zu den Komplexen (Ph3PAu)2mnt (3), (Bu4N)[Ph3PAu(mnt)] (4), (Ph3PAu)2Pt(mnt)2 (5) und (Ph3PAu)2dmit (10) bzw. [(CO)5Re]2Ni(mnt)2 (6), (Bu4N){[(CO)5Re]M(mnt)2} (M = Ni, Pt, 7, 8), [(CO)5Re]2(mnt)2 (9) und [(CO)5Re]2Ni(dmit)2 (11) um. Die Strukturen von 3, 4 und 5 wurden röntgenographisch bestimmt. In 4 ist der Chelatligand symmetrisch an das AuI-Atom gebunden. Im Kristall von 3 entstehen durch schwache AuAu-Wechselwirkungen Ketten (dAuAu = 309 pm). Die trans-anti-Konfiguration im Komplex 5 wird aus sterischen Gründen auch für die analogen Komplexe 6 und 11 angenommen. Während 1 mit K2[M(dto)2] (dto = dithiooxalato, M = Pd, Pt) die erwarteten Bis(triphenylphosphangold)-Addukte 12 und 13 bildet, ergibt 2 [(CO)5Re]2 (dto)2 (14) als stabiles Endprodukt. Das Triphenylphosphangold-Analogon 15 erhält man durch Reaktion von 1 mit K2dto. [(CO)5Re]2FeNO(dto)2 (16) kann als primäres Produkt der Reaktion von 2 mit [Fe(NO)(dto)2]2- isoliert werden. Re(CO)5+ und Ph3PAu+ können an die verbrückenden S-Atome von [(ON)2Fe(-S)2Fe(NO)2]2- unter Bildung von 17 und 18 addiert werden

Predicting Stable Molecular Structures for (RNC)(2)(AuX)-X-I Complexes

Calculations have been performed at the MP2 and DFT levels for investigating the reasons for the difficulties in synthesizing bis(isocyanide)gold(I) halide complexes. Three-coordinated gold(I) complexes of the type (R3P)(2)(AuX)-X-I (1) can be synthesized, whereas the analogous isocyanide complexes (RNC)(2)(AuX)-X-I (2) are not experimentally known. The molecular structures of (R3P)(2)(AuX)-X-I (X = Cl, Br, and I) and (RNC)(2)(AuX)-X-I with X = halide, cyanide, nitrite, methylthiolate, and thiocyanate are compared and structural differences are discussed. Calculations of molecular properties elucidate which factors determine the strength of the gold-ligand interactions in (RNC)(2)(AuX)-X-I. The linear bonding mode of RNC favors a T-shaped geometry instead of the planar Y-shaped trigonal structure of (R3P)(2)(AuX)-X-I complexes that have been synthesized. An increased polarity of the Au-X bond in 2 leads to destabilization of the Y-shaped structure. Chalcogen-containing ligands or cyanide appear to be good X-ligand candidates for synthesis of (RNC)(2)(AuX)-X-I complexes.Peer reviewe

Database studies of halide ion pairs with bridging water and NH₂ amino molecules

Studies using the Cambridge Structural Database have shown that hydrogen-bond linearity is a major factor determining the structure of halide ion pairs bridged by water and NH2-containing molecules and that the halide-halide distances in these ion pairs are geometrical consequences of this fact
