<div dir="ltr"><div><div><div>Thank You All.<br></div><br>I benefited from all of you on mailing list. You are absolutely right I should learn instead of spoon feeding. I can understand fully that experts are already handling the burden of below average questions. <br>
<br>Inspite of all your recommendation I wish that someone should suggest a road map of topics that leads to solution of making new structure in WIEN2k. I see many emails on mailing list that suggest the similar kind of problem of making structure for a specific space group. I really wanted to learn this but always lost in multiple topics. Many of seniors to whom I know personally know can not solve this problem. Just suggesting, that it will beneficial for newcomers if someone can prepare a tutorial on this issue. We sometimes do not work on compounds just because we cannot make structure file in wien2k.<br>

I need ideal positions for three atoms and then I will relax the structure to actual positions for this compound. Modeling a material is possible without experimental results.

Dear Wien2k experts<br>
<br>
I am reporting this difficulty after going through mailing list and<br>
literature review. Kindly guide how can I generate structure file with<br>
the following information.<br>
<br>
Compound Formula: V3S7Cl<br>
Space Group: C mmm#65 Orthorhombic<br>
lattice parameters: a=20.6 b=3.8, c=3.9<br>
<br>
I need *general structure file* for this compound I will try to remove<br>
error associated with RMTs and other initializing parameters by my self.<br>
<br>
Alternatively,<br>
<br>
If I select 3 atoms in the structure generation and I insert all the<br>
parameters as stated above then I just miss the position of three atoms<br>
in the structure file. In order to fill the positions I checked the<br>
wycoff psoitions from the Bilbao Crystallographic server but I am unable<br>
to understand which position should I give. *If this approach is<br>
correct* then kindly just *provide the positions* which I can fill at<br>
least ideal positions for this kind of space group so that I can fill<br>
and later on I will relax my structure to get actual positons. Kindly do<br>
guide.<br>
<br>
Best Regards<br>
Naseem Hassan<br>
