PREPARATION AND CHARACTERIZATION OF [Ni (MAP) ] ; H- MAP = 2- (METHYLAMINO) PYRIDINE H. Aghabozorg* and H. H. Monfared
We have recently synthesized [Ni (MAP) ] complex [H-MAP= 2- (methylamino) pyridine]. 2- (Methy1amino)pyridine reacts with MeLi in THF and generates the lithium salt (Li-MAP). Further reaction of NiCl with two equivalent of this ligand in THF leads to the formation of a dark red solution. Analytical data, molecular weight, and magnetic susceptibility of this complex confirm the formula [N...
متن کاملOn the Finsler modules over H-algebras
In this paper, applying the concept of generalized A-valued norm on a right $H^*$-module and also the notion of ϕ-homomorphism of Finsler modules over $C^*$-algebras we first improve the definition of the Finsler module over $H^*$-algebra and then define ϕ-morphism of Finsler modules over $H^*$-algebras. Finally we present some results concerning these new ones.
متن کاملLiouville Closed H-fields
H-fields are fields with an ordering and a derivation subject to some compatibilities. (Hardy fields extending R and fields of transseries over R are H-fields.) We prove basic facts about the location of zeros of differential polynomials in Liouville closed H-fields, and study various constructions in the category of H-fields: closure under powers, constant field extension, completion, and buil...
متن کاملOn Chains in H-Closed Topological Pospaces
We study chains in an H-closed topological partially ordered space. We give sufficient conditions for a maximal chain L in an H-closed topological partially ordered space such that L contains a maximal (minimal) element. Also we give sufficient conditions for a linearly ordered topological partially ordered space to be H-closed. We prove that any H-closed topological semilattice contains a zero...
متن کاملParametrizing Simple Closed Geodesy on Γ\h
We exhibit a canonical geometric pairing of the simple closed curves of the degree three cover of the modular surface, Γ\H , with the proper single self-intersecting geodesics of Crisp and Moran. This leads to a pairing of fundamental domains for Γ with Markoff triples. The routes of the simple closed geodesics are directly related to the above. We give two parametrizations of these. Combining ...
