| description | 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 |
