In the title compound, [CuMoO(4)(C(8)H(20)N(4))]·H(2)O, the Cu(II) atom is coordinated by four N atoms of the 1,4,7,10-tetra-aza-cyclo-dodecane (cyclen) ligand and one O atom of the molybdate unit in a distorted square-pyramidal environment. The water mol-ecules are linked to the complex unit to form centrosymmetric dimers [R(4) (4)(12) and R(4) (4)(16)] and discrete D(3) (2)(9), D(3) (3)(11) a...

An ab initio study has been performed for the electronic, spectroscopic, and chemical properties of the most stable configuration of the (CdO)n nanoclusters by employing B3LYP-DFT/LanL2DZ method. Different isomers were optimized to obtain structural stability and numerous chemical parameters such as dipole moment, ionization potential, etc. We report here the vibrational frequencies of the most...

Given a set Un = {0, 1, ..., n−1}, a collectionM of subsets of Un that is closed under intersection and contains Un is known as a Moore family. The set of Moore families for a given n, denoted by Mn, increases very quickly with n, thus |M3| is 61 and |M4| is 2480. In [1] the authors determined the number for n = 6 and stated a 24hcomputation-time. Thus, the number for n = 7 can be considered as...

We show that any finite system S in a characteristic zero integral domain can be mapped to Z/pZ, for infinitely many primes p, preserving all algebraic incidences in S. This can be seen as a generalization of the well-known Freiman isomorphism lemma, which asserts that any finite subset of a torsion-free group can be mapped into Z/pZ, preserving all linear incidences. As applications, we derive...

Electron-rich aza-aromatic compounds such as indoles is structures of particular interest and importancein organic chemistry. A useful procedure for the preparation of new 3-sulfenyl indole derivatives using S-alkyl or S-arylthiophthalimides as sulfenylating agents and poly(N, N′-dibromo-N-ethyl-naphthyl-2,7-disulfonamide) as novel catalyst is described. The method represents an efficient prepa...
