Complex [Zn(Im) 2] n crystallizes in tetragonal space group I4 1 cd
with a = 2 357 2(3) pm
b =2 357 2(3) pm
c =12 467(2) pm
V =6 927(2)×10 9 pm 3
Z =32 The asymmetric unit of [Zn(Im) 2] n consists of two crystallographically independent Zn(Ⅱ) atoms
which adopt very similar coordination environments Each Zn(Ⅱ) atom is tetrahedrally coordinated by four imidazolate N atoms from different imidazolate group Each imidazolate ligand in [Zn(Im) 2] n acts as a μ 2 bridge
linking a pair of adjacent Zn(Ⅱ) atoms with the Zn…Zn separation at range of 591 8(1) ̄602 9(1) pm The Zn(Ⅱ) atoms and the μ 2 imidazolate moieties in [Zn(Im) 2] n are alternatively connected into a three dimentional network in the solid state
