PREPARATION AND CRYSTAL STRUCTURE OF CaCl .[OC(NH ) ]
Authors: not saved
Abstract:
Calcium dichloride tetra urea was prepared by the reaction of calcium chloride with urea in aqueous solution. The crystals are monoclinic, a= 7.633, b= 12.45 1, c= 8.118 ?,? = 113.17, Z = 4, space group P 2,/a. The crystal structure was determined by single crystal X-ray methods and refined to R= 0.041. The calcium atoms are coordinated to four oxygen atoms of urea and to two chloride ions. The coordination polyhedra are distorted octahedral

Black single crystals of MnBiS2Br were obtained by the reaction of stoichiometric amounts of -MnS, Bi, S, and BiBr3 (3:2:3:1) at 600 C for 4 weeks. The compound crystallises in the monoclinic system, space group C2=m, with a1⁄4 12.767(2), b1⁄4 3.9468(4), c1⁄4 9.574(1) Å, 1⁄4 90.87(2) , and Z1⁄4 4. The crystal structure refinement based on 720 reflections converged at R1⁄4 0.0244 and wR21⁄4 0.05...
