In the title compound, C(4)H(7)N(3)O·C(2)H(6)OS, creatinine [2-amino-1-methyl-1H-imidazol-4(5H)one] exists in the amine form. The ring is planar (r.m.s. deviation for all non-H atoms = 0.017 Å). In the crystal, two creatinine mol-ecules form centrosymmetric hydrogen-bonded dimers linked by pairs of N-H⋯N hydrogen bonds. In addition, creatinine is linked to a dimethyl sulfoxide mol-ecule by an N...
The asymmetric unit of the title compound, {(C(4)H(7)N(2))[CdCl(3)(H(2)O)]}(n), contains one 1-methyl-1H-imidazol-3-ium cation, one Cd(II) atom, three Cl atoms and one water mol-ecule. Adjacent Cd ions are inter-connected alternately by paired Cl(-) bridges to generate an infinite one-dimensional coordination chain along the b axis. In the chain, the crystallographically unique Cd(II) atom, wit...
Herein, we report the synthesis of two novel coordination polymers using a combination imidazole-containing ligands, namely 1,3,5-tris((1H-imidazol-1-yl)methyl)benzene (L1) and 3,3?,5,5?-tetra(1H-imidazol-1-yl)-1,1?-biphenyl (L2) carboxylate ligand derived from 4,4?-biphenyldicarboxylic acid (H2BPDC). The structures [Ni(L1)(BPDC)]·2H2O (1·2H2O), which exhibits 2-fold interpenetrated 3D ? archit...
Two copper complexes, 1 and 2, with tridentate N-donor ligands, L(1) and L(2) [L(1)= (1-methyl-1H-imidazol-2-ylmethyl)-(2-pyridin-2-yl-ethyl)amine, L(2) = (2-pyridin-2-yl-ethyl)-pyridin-2 yl-methylamine] respectively, have been synthesized and characterized. On exposure to nitric oxide, the copper(II) centers in complexes 1 and 2 were found to undergo reduction in various solvents. In acetonitr...
In the title complex, [Co(C(13)H(14)N(3)O(3))(2)(H(2)O)(2)], the Co(II) atom has a distorted octa-hedral coordination, formed by four N atoms from two (±)-2-(5-isopropyl-5-methyl-4-oxo-4,5-dihydro-1H-imidazol-2-yl)nicotinate ligands and two O atoms from two water mol-ecules. Intra-molecular N-H⋯O and O-H⋯O hydrogen bonds are present. In the crystal, inter-molecular O-H⋯O hydrogen bonds link the...
چکیده: خواص مولکولی 5کمپلکسni(ii) شیف باز که شامل کره کئوردیناسیون nnos: methyl-2-{n-[2-(acetone)triflourolidynenitrilo]ethyl}amino-1-yclopentenedithi-ocarboxylate l1= methyl-2-{n-[2-(acetone)ethylidyneni-trilo]ethyl}amino-1-lopentenedithi-ocarboxylate l2= methyl-2-{n-[2-(acetone)phenylidy-nenitrilo]ethyl}amino-1-cyclopentenedithi-ocarboxylate l3= methyl-2-{[1-methyl-2-(ace-tone)ethylid...
Piperazine derivatives have been identified as new antidiabetic compounds. Structure-activity relationship studies in a series of 1-benzyl-4-alkyl-2-(4',5'-dihydro-1'H-imidazol-2'-yl)piperazines resulted in the identification of 1-methyl-4-(2', 4'-dichlorobenzyl)-2-(4',5'-dihydro-1'H-imidazol-2'-yl)piperazine, PMS 812 (S-21663), as a highly potent antidiabetic agent on a rat model of diabetes, ...
Single crystals of the title compound, (imidazolium-2-yl)phenyl-phosphinate monohydrate, C(9)H(9)N(2)O(2)·H(2)O, were ob-tained from methanol/water after deprotection and oxidation of bis-(1-diethoxy-methyl-imidazol-2-yl)phenyl-phosphane. In the structure, several N-H⋯O and P-O⋯H-O hydrogen bonds are found. π-π inter-actions between the protonated imidazolyl rings [centroid-centroid distance = ...
In the title compound, [Zn(C(23)H(14)O(6))(C(14)H(14)N(4))](n), the Zn(II) ion is four-coordinated in a distorted tetra-hedral geometry. The 1,3-bis-(imidazol-1-ylmeth-yl)benzene and 2,2'-dihy-droxy-1,1'-methyl-enebis(naphthalene-3-carboxy-l-ate) ligands con-nect the Zn(II) ions alternately in different directions, forming a layered structure parallel to the ac plane. Topological analysis revea...
