Single crystals of monoclinic Nd(2)W(2)O(9) were obtained by growth from tungsten borate flux in an atmosphere of air. The crystal structure consists of chains of distorted [WO(6)] octa-hedra that run along the c axis of the structure, and of [NdO(9)] polyhedra that are connected via common faces and common edges to form a three-dimensional framework.

The seven-membered ring of the title compound, C(17)H(20)N(2)O(2), adopts an approximate boat conformation while the cyclo-hexyl ring adopts a chair conformation. In the crystal, adjacent mol-ecules are linked by N-H⋯O hydrogen bonds into a zigzag chain running along the c axis of the monoclinic unit cell.

Since that time, new data have become available, and these have been incorporated into the monograph and taken into consideration in the present evaluation. 1.1.2 Structural and molecular formulae and relative molecular mass o Il H2C= CH-C-NH2 Relative molecular mass: 71.08 C3HsNO 1.1.3 Chemical and physical properties of the pure substance (a) Description: White crystalline solid (monoc...

3-(2-Bromo-4-(1-methylethyl)phenyl)-1,1-dimethylurea was synthesized and structurally characterized at 296 K, 200 K and 140 K. A reversible thermal phase transformation was observed at ~170–180 K. On cooling, the structure transforms from a monoclinic to a triclinic crystal system. The isopropyl group is disordered above the phase transition temperature but is ordered below the transition tempe...

Dihydrodipicolinate synthase from Mycobacterium tuberculosis (DHDPS, DapA, Rv2753c) has been cloned, heterologously expressed in Escherichia coli, purified using standard chromatographic techniques and crystallized in a monoclinic crystal form. Preliminary diffraction data analysis suggests the presence of two independent tetramers in the asymmetric unit in almost the same relative orientation.

Polar organic nonlinear optical material, L-tartaric acid single crystals have been grown from slow evaporation solution growth technique. Single crystal X-ray diffraction study indicates that the grown crystal crystallized in monoclinic system with space group P21.
