meso-[5,5,7,12,12,14-Hexamethyl-1,4,8,11-tetraazacyclotetradeca-1(14),7-diene]nickel(II) dibromide dihydrate
The asymmetric unit of the title complex, [Ni(C(16)H(32)N(4))]Br(2)·2H(2)O, contains two [Ni(C(16)H(32)N(4))](2+) cations, four Br(-) anions and four uncoordinated H(2)O mol-ecules. The Ni atoms are in a slightly distorted square-planar coordination by the four macrocyclic N atoms, which are almost coplanar [N-N-N-N torsion angles of 2.97 (6) and 3.12 (7)°]. In the crystal, a network of N-H⋯Br,...
متن کاملThe crystal structure of guanosine dihydrate and inosine dihydrate.
Crystals of the dihydrates of guanosine (C10H13NsOs) and inosine (C10H12N405) are nearly isostructural. They are monoclinic, space group P21, with cell dimensions a= 17·518, b= 11 ·502, c= 6·658 A, P=98·17° (guanosine) and a=17·573, b=11·278, c=6-654A, P=98·23° (inosine). There are two nucleoside molecules and four water molecules per asymmetric unit. Data were collected on an automated diffrac...

Accepted for publication 20 April 1993 Abstract Objectives-Little is known about the effect on crystal induced neutrophil responses of the opsonisation of calcium pyrophosphate dihydrate (CPPD) (triclinic) crystals with components of serum and plasma. The purpose ofthis study was to determine the effects of precoating CPPD crystals with plasma, serum, complement depleted serum, and IgG on a ful...
متن کاملBis(tetraethylammonium) oxalate dihydrate
The title compound, 2C(8)H(20)N(+)·C(2)O(4) (2-)·2H(2)O, synthesized by neutralizing H(2)C(2)O(4)·2H(2)O with (C(2)H(5))(4)NOH in a 1:2 molar ratio, is a deliquescent solid. The oxalate ion is nonplanar, with a dihedral angle between carboxyl-ate groups of 64.37 (2)°. O-H⋯O hydrogen bonds of moderate strength link the O atoms of the water mol-ecules and the oxalate ions into rings parallel to t...
متن کامل3,3′-Diazenediyldiphthalic acid dihydrate
In the crystal structure of the title compound, C(16)H(10)N(2)O(8)·2H(2)O, the organic mol-ecule is located on a centre of symmetry. The two benzene rings are parallel, but not coplanar, as indicated by N=N-C-C torsion angles involving the azo group of 12.1 (5) and -168.2 (3)°. The organic mol-ecule and the water mol-ecule are linked by O-H⋯O hydrogen bonds, forming a three-dimensional network.
