The title Pb(II) coordination polymer, [PbCl(2)(C(13)H(14)N(2))], was prepared by the hydro-thermal reaction of PbCl(2) with 4,4,-trimethyl-enedipyridine in a 1:1 ratio. It exhibits a two-dimensional layered structural motif consisting of PbCl(2) chains and the flexible bridged 4,4'-trimethyl-enedipyridine ligand. The connections result in a cavity of about 4 × 15 Å.

In the mol-ecule of the title compund [systematic name: N-butyl-N-ethyl-2,5,6-trimethyl-7-(2,4,6-trimethyl-phen-yl)-7H-pyrrolo[2,3-d]pyrimidin-4-amine], C(24)H(34)N(4), the pyrrolopy-rimidine ring system is nearly planar, its five- and six-membered rings forming a dihedral angle of 5.3 (2)°. The benzene ring is nearly orthogonal to the central ring system. The N atom carrying the ethyl and n-bu...

Some oxime ether derivatives of α-ionone (4-(2,6,6-trimethyl-2-cyclohexen-1-yl)-3-buten-2-one) have been synthesized. Reaction of 4-(2,6,6-trimethyl-2-cyclohexen-1-yl)-3-buten-2-ketoxime with various chloro and fluoro aromatic and hetero aromatic compounds gave the corresponding oxime ether derivatives via aromatic nucleophilic substitution (SNAr). The structures of these co...

The objectives of this research was to determine the chemical composition of roscoe extract from methanol and evaluation of antibacterial activity. The phytochemical compound screened by GC-MS method. Forty eight bioactive phytochemical compounds were identified in the methanolic extract of Zingiber officinale. The identification of phytochemical compounds is based on the peak area, retention t...
