Abstract: The algebraic formulas of 1.5 and 2.5 rank are given for four space groups P2_1, Pn, Pnα2_1, P2_12_12_1. It is better that the results of applying them to estimating general type of phases for four correspondent crystal structures. And a method of transforming algebraic formulas from 1(2) rank into 1.5(2.5) rank is proposed.

Key words: Crystal structure determintion, Direct method, Estimating general type of phases
