Poly[tris-(2-amino-butan-1-ol)copper(II) [hexa-kis-μ-cyanido-κ :-tetra-copper(I)] bis-(2-amino-butan-1-olato)aqua-copper(II) monohydrate].

The title structure, {[Cu(CHNO)][Cu(CN)]·[Cu(CHNO)(HO)]·HO} , is made up of diperiodic honeycomb CuCN networks built from [Cu(CN)] units, together with two independent Cu complexes: six-coord-inate [Cu(CHCHCH(NH)CHOH)] cations, and five-coordinate [Cu(CHCHCH(NH)CHO)·HO] neutral species. The two Cu complexes are not covalently bonded to the CuCN networks. Strong O-H⋯O hydrogen bonds link the Cu complexes into pairs and the pairs are hydrogen bonded into chains along the crystallographic axis the hydrate water mol-ecule. In addition, O-H⋯(CN) and N-H⋯(CN) hydrogen bonds link the cations to the CuCN network. In the honeycomb polymeric moiety, all bridging cyanido ligands are disordered over two orientations, head-to-tail and tail-to-head, with occupancies for C and N atoms varying for each CN group.
