[Relation between complexes iotramolecular transfer and structure of [M(SS) (NN)](M = Zn2+, Cd2+)].

The title complexes of [M(SS)(NN)](M = Zn2+, Cd+; SS = 1,2-dicyano 1,2-ethylene -dithiolate or maleonitriledithiolate; NN = 5-nitro-1,10 phenanthroline) were synthesized. The electronic absorption spectra of complexes [M(SS)(NN)] in DMSO, DMF, acetone and Py were reported. The spectra absorption bands 270-280 nm, 320-350 nm and 350-390 nm are the intraligand pi(b) --> pi* transfer of ligand mnt(2-) and 5-NOz-phen.

[Changes of adenylate cyclase on cerebral regions related to mophine dependence in rats].

Objective: To observe the changes of adenylate cyclase(AC) on cerebral regions related to morphine dependence in rats and investigate the relationship between the enzymological changes and the mechanism of morphine dependence.

Methods: The technique of enzyme-histochemistry was used to detect the variations of AC of special seven cerebral regions including frontalis cortex, lenticula, corpus amygdaloideun, substantia nigra, hippocampus, periaqueductal gray and locus coerleus in morphine dependent rats. The enzymological changes were observed by optical microscope.

[Infrared spectra and coordinated mode of manganese (II), iron (II), cobalt (II) complexes with dithiolene and 1, 10-phenanthroline-5, 6-dione ligands].

The infrared spectra and far-infrared spectra of M(mnt)(phen-5, 6-dione) [M= Manganese(II), Iron(II), Cobalt(II). mnt2- = 1, 2-dicyano-1, 2-ethylenedithiolate or maleonitriledithiolate, phen-5, 6-dione = 1, 10-phenanthroline-5, 6-dione] are reported in detail. In infrared spectra and far-infrared, characteristic v (C[triplebond]N) , v (C==)) , (C==C) v (C-N), v (C-S), v (M-S) and V(M-N) are very strong.
