Notes: Indium(III) and tin(IV) thiocarboxylates were prepared and characterized on the basis of their IR, 13C- and 19Sn-NMR data. Indium tris(thiobenzoate) (1) decomposes into a sulfido complex In (S)[S(O)CPh] (2a). The corresponding tris(thioacetate) In[S(O)CMe]3 is thermally too unstable to be isolated. The anionic tetrakis complex [Et3NH]{In[S(O)CPh]4} (3) was characterized by X-ray crystallography which revealed a distorted tetrahedral coordination at the In atom. X-ray diffraction analysis of the complexes BuSn[S(O)CPh]3 (4) and Cl2Sn[S(O)CPh]2 (7) showed distorted tetrahedral and cis-octahedral structures, respectively.

Notes: Abstract Diurnal patterns of leaf water potential (ΨW), canopy net photosynthetic rate (P N), evapotranspiration rate (E), canopy temperature (Tc), and water use efficiency (WUE) of clusterbean [Cyamopsis tetragonoloba (L.) Taub., cv. Desi] were studied at six phenological stages of plant development under field conditions at CCS Haryana Agricultural University, Hisar. The highest P N, E, and WUE were observed at pod initiation stage (61 DAS). Daily maxima of P N were usually between 11:00 to 14:00 h while those of E and WUE between 12:30 and 16:00 h. P N was mainly dependent on photosynthetically active radiation and E on air temperature (Ta) but the relationships varied at different growth stages. WUE declined with the increase in T a. At mid-day, ΨW was highest during pod initiation.
