In the title compound, cis-[PtCl₂(NH₃)₂]·C₃H₇NO, the metal complex mol-ecules are stacked parallel to the b axis, forming close Pt⋯Pt inter-actions of 3.4071 (7) and 3.5534 (8) Å and weak N-H⋯Cl hydrogen bonds between the ammine ligand and the Cl atoms of the neighboring complex. Conventional N-H⋯O hydrogen bonds are formed between ammine ligands and the O atom of adjacent N,N-dimethyl-formamid...
A platinum(II) and 3 platinum! l\ i ammine/cycloalkylamine ho mologous series were evaluated for cytotoxicity and biochemical pharmacology in murine leukemia L1210/0, cis-diamminedichloroplatinum(H)-resistant 1.1210/1)1)1', and diaminocyclohexaneplatinum-resistant L1210/l,2-diaminocyclohexane (DACH) cells. Within each se ries, which contained 4 homologues with differing alicyclic (cycloalkyl) r...
Six new dicationic 2D nonlinear optical (NLO) chromophores with pyrazinyl-pyridinium electron acceptors have been synthesized by nucleophilic substitutions of 2,6-dichloropyrazine with pyridyl derivatives. These compounds have been characterized as their PF(6)(-) salts by using various techniques including electronic absorption spectroscopy and cyclic voltammetry. Large red shifts in the intens...
Recently we reported the profound effects of second-sphere crown ether binding upon the redox energetics and intervalence spectroscopy of selected mixed-valence (Crowd metal complex associatino is driven primarily by ether oxygen/ ammine hydrogen interactions, where the H-bond-donating capability of NH3 is greatly enhanced by coordination to a transition-metal cation.) For delocalized species s...
Mixed ligand complexes of zinc (II) involving either mercaptyl thiazolidinone (1) [2-(2hydroxy benzoyl)-3-N-(2-mercaptyl)-1-Thiazolidin-4-one] or pyridine thiazolidinone (2) [ 2-(2hydroxy benzoyl-3-N-(2-Pyridinyl)-1-Thiazolidin-4-one] alone and along with thiourea have been obtained by partial or complete replacement of the strongly coordinated ammonia of ammine complex. All the products have b...
Worth the excitement: Highly reactive oxygen and nitrogen species are generated by photoactivation of the anticancer platinum(IV) complex trans,trans,trans-[Pt(N3 )2 (OH)2 (MA)(Py)] (MA=methylamine, Py=pyridine). Singlet oxygen is formed from the hydroxido ligands and not from dissolved oxygen, and ammine ligands are products from the conversion of azido ligands to nitrenes. Both processes can ...
Mixed ligand complexes of copper (II), involving either Mercaptyl thiazolidinone (1) [2-(2hydroxy benzoyl)-3-N-(2-mercaptyl)-1-Thiazolidin-4-one] or Pyridine thiazolidinone (2) [ 2-(2hydroxy benzoyl-3-N-(2-Pyridinyl)-1-Thiazolidin-4-one] alone and along with Thiourea were synthesized by partial or complete replacement of the strongly coordinated ammonia of ammine complex. All the products have ...
The asymmetric unit of the title complex salt, [Cr(C10H24N4)(NH3)2][ZnCl4]Cl·H2O, is comprised of four halves of the Cr(III) complex cations (the counterparts being generated by application of inversion symmetry), two tetra-chlorido-zincate anions, two chloride anions and two water mol-ecules. Each Cr(III) ion is coordinated by the four N atoms of the cyclam (1,4,8,11-tetra-aza-cyclo-tetra-deca...
