I don't love this voicing but it is commonly used. A better choice when it is possible is to use the Dom. 9th/Min.6th grip from the previous section that also works as a 1/2 diminished in first inversion (that means it has the 3rd in the bass).
Or try this one too: 1/2 diminished with b5 in bass, in this case D 1/2 diminished/Ab - see additional chart below.
